We now have reactions coming in from Indian opposition leaders, who have expressed support for the strikes.

Mallikarjun Kharge, chief of the main opposition Congress party, says "national unity and solidarity is the need of the hour". He says that since last month's attack in Indian-administered Kashmir, his party has "categorically stood with the armed forces and the government to take any decisive action against cross-border terror".

Asaduddin Owaisi, chief of the All India Majlis-e-Ittehadul Muslimeen (AIMIM), has also welcomed the "surgical strikes" carried out by India on "terror camps in Pakistan".

News of the strikes comes as several Indian states have been holding security drills for civilians.

The federal home ministry had issued an order earlier this week, asking for drills to be conducted across 244 districts in the country with the aim of assessing and enhancing "civil defence mechanisms".

The ministry said the objective was to assess the effectiveness of India's air raid warning systems, control rooms, evacuation plans, crash blackout measures and civil defence services.

The order said the exercise aimed to train civilians and students "to protect themselves in the event of a hostile attack". It did not mention Pakistan or last month's attack in Indian-administered Kashmir.

Footage shared by news agency ANI on Tuesday showed volunteers and officials carrying out rehearsals in different states.

We'll bring you some photos and videos from more drills scheduled for Wednesday.

Indian media reports say Defence Minister Rajnath Singh has spoken to the chiefs of the army, air force and navy to discuss the airstrikes.

Indian officials are expected to brief the media on the military operation at 10:00 local time (04:30GMT).

The Pakistan Peoples Party (PPP) has condemned India's "aggression against Pakistan by targeting civilian populations across the border".

The PPP is one of three major political parties in Pakistan and is chaired by Bilawal Bhutto Zardari, the son of the country's president, Asif Ali Zardari.

The party added in a post on X that India's "unprovoked" attack was a violation of "international law, the UN Charter and Pakistan's sovereignty".

"Indian provocations will be countered with full force and unwavering determination to protect Pakistan's sovereignty and territorial integrity," it said.

India says it launched "targeted strikes on nine terrorist infrastructure sites" in Pakistan and Pakistan-administered Kashmir and that no military, civilian or economic facilities were targeted.

It says the strikes are in response to the April militant attack in Pahalgam that left 26 people dead.

Things have been moving fast in the hours since India launched airstrikes on Pakistan and Pakistan-administered Kashmir. If you're just joining us, here's a quick recap:

• Delhi says it has struck nine sites in Pakistan and Pakistan-administered Kashmir in a "focused, measured and non-escalatory" manner
• Pakistan has confirmed three locations have been hit in what it described as a "cowardly attack". Foreign Minister Muhammad Ishaq Dar has said eight civilians have died and 35 others have been injured. India has not commented on the toll.
• Pakistan has said Islamabad will respond "at a time and place of its choosing".
• Reuters and AFP quote Indian army sources as saying three Indian civilians have been killed in military action by Pakistani troops in Indian-administered Kashmir. Official confirmation is awaited.
• Residents in Muzaffarabad in Pakistan-administered Kashmir told the BBC they were jolted awake by huge explosions. Locals in Indian-administered Kashmir said they heard explosions near the Line of Control, the de-facto border between the two countries.
• Relations between India and Pakistan - both nuclear-armed states - have declined sharply following a deadly militant attack on tourists in Kashmir last month.
• Pakistan has denied involvement in the attacks, but Indian police say two of the four militants they suspect for the attack were Pakistani citizens. A manhunt by the security forces is still under way.
• Both India and Pakistan have announced a range of retaliatory measures against one another including closing borders and suspending a river water treaty. Troops from both sides have also traded small arms fire.

This is a fast developing story. Stay with us for further updates.

Islamabad has informed the UN Security Council (UNSC) about the "blatant aggression by India and the threat it posed to international peace and security", Pakistan's foreign ministry says in a statement.

"UNSC has been informed that Pakistan reserves the right to respond appropriately to this aggression at a time and place of its choosing, in accordance with its right to self-defence as enshrined in Article 51 of the United Nations Charter," it adds.

Iranian Foreign Minister Seyed Abbas Araghchi is due to arrive in Delhi later on Wednesday. He is scheduled to meet President Droupadi Murmu and Foreign Minister S Jaishankar, the Indian foreign ministry said, external.

Araghchi was earlier this week in Islamabad where he held talks with Pakistani army chief Gen Syed Asim Munir and Prime Minister Shehbaz Sharif. The two sides discussed bilateral relations, border co-operation and enhancing security along their shared borders, according to the statement released by Tehran.

Iran has offered to mediate between India and Pakistan as tensions between the two neighbours escalate.

This is the moment for some well-timed mediation.

With India having struck and Pakistan warning of a counter-strike, escalation risks are higher now than they’ve been at any time going back quite a few years. Based on the nature of these initial actions, the chance of further hostilities is quite likely.

The international community appears to be in agreement that the attack in Pahalgam last month should be strongly condemned, but that de-escalation is essential.

No-one wants a war with the world already on fire, and especially one between two nuclear rivals. This is the time for states with good relations with both India and Pakistan - the US but also the Arab Gulf states - to work the phones and urge the two to look for off ramps before nuclear escalation risks set in.

Schools in Pakistan's capital Islamabad and in Punjab province have been shut, as the country says it is preparing to respond to the Indian strikes.

Earlier on Wednesday, India said it had launched strikes on nine sites in Pakistan and Pakistan-administered Kashmir in response to last month's militant attack in Pahalgam that killed 26 people. Delhi blames Islamabad for the killings - a charge it denies.

In the last few days, Pakistan’s military and government had been offering journalists escorted visits to Bahawalpur and areas near Muzaffarabad - sites that Pakistan’s military says are among the areas hit by the strikes.

Islamabad said it wanted to debunk India's claims that these were militant training camps.

The country's Foreign Minister Muhammad Ishaq Dar has now said there were eight civilian casualties and 35 injured.

India has not responded to these claims.

Reuters and the AFP news agency are reporting that India's army has said three Indian civilians have been killed in military action by Pakistani troops in Indian-administered Kashmir.

Pakistan Prime Minister Shahbaz Sharif has called a meeting of its National Security Committee (NSC) at 10:00PST (05:00 GMT) on Wednesday, according to the country's information minister.

Earlier on Wednesday, India launched strikes on nine sites in Pakistan and Pakistan-administered Kashmir. Delhi has said that the strikes were in response to the militant attack in Pahalgam that killed 26 people.

Pakistan has called the strikes a "cowardly attack" and that it would respond to them at a place and time of its choosing.

US Secretary of State Marco Rubio has said on X that he is monitoring the situation between India and Pakistan closely.

Earlier today, the Indian embassy in the US said that India's National Security Adviser Ajit Doval had spoken to Rubio "and briefed him on the actions taken".

President Donald Trump had also responded to media questions about India's strike, calling it "a shame".

"I just hope it ends very quickly," Trump said while speaking at the White House in Washington DC.

Rubio said he echoed the US president's comments "that this hopefully ends quickly". He also said that he would continue to engage with both Indian and Pakistani leadership "towards a peaceful resolution".

Several Indian airlines have also announced the cancellation of flights to Indian-administered Kashmir and to some cities in border states such as Rajasthan and Punjab.

SpiceJet said that airports in parts of northern India, including Dharamshala, Leh, Jammu, Srinagar and Amritsar, were closed, which impacted its flights from these locations. IndiGo Airlines posted on X that its flights to and from these cities were impacted because of changing airspace conditions.

Air India said it had cancelled all its flights to and from Jammu, Srinagar, Leh, Jodhpur, Amritsar, Bhuj, Jamnagar, Chandigarh and Rajkot cities till noon local time.

The airline also said it had diverted two international flights en route to Amritsar in Punjab state to capital Delhi.

As details emerge from tonight’s attacks, Pakistani authorities have announced the closure of airspace regions covering the major cities of Lahore and Karachi. The closure is in place until 19:20 GMT.

Several major airports fall into these regions, including Islamabad International Airport. There’s already a significant impact on flights in the region, and several planes have diverted from Pakistan, according to flight tracking provider FlightRadar24.

In a post on social media, external, the firm showed diversions by Finnair, Emirates, Turkish Cargo and Saudia.

In a statement to CNN, Air France said it had suspended flights over Pakistan until further notice, and was “adapting its flight schedule and flight plans to and from certain destinations”. German carrier Lufthansa has also told Reuters news agency that it was “avoiding Pakistani airspace until further notice”.

We can bring you reaction from Pakistan's Minister of Information Attaullah Tarar who has just been speaking to the BBC.

Reacting to news of Indian strikes, he said: "They have crossed our limits."

He repeated earlier remarks from the military spokesperson about reciprocal strikes.

"This attack is unjustified and an absolutely blind aggression," he said. "We will obviously retaliate... Our response is on the ground and in the air."

Pakistan had warned it believed an attack was coming.

And in the dead of night, that belief was confirmed.

The Pakistani military says five locations were targeted, some of them in Pakistan-administered Kashmir. These were areas that the government had encouraged journalists to visit, and said were locations that India claimed were militant training camps.

Since the deadly attack in Indian-administered Kashmir last month, Prime Minister Narendra Modi had vowed he would hold the perpetrators to account.

Pakistan has consistently denied any involvement and called for an independent investigation. The government had been calling on world leaders and the UN Security Council to help calm tensions.

The nature of any casualties and Pakistan's response will be crucial in determining whether this military confrontation escalates.
