Blast kills two Chinese near Pakistan's Karachi airport

A massive blast rocked a road near the airport of Karachi, Pakistan's largest city

Two Chinese nationals have been killed and at least 10 people injured in a suspected suicide attack near Karachi airport in Pakistan.

A third body, not yet officially identified, is thought to be that of the attacker, the BBC understands.

The Chinese embassy in Pakistan said the explosion on Sunday night was a "terrorist attack" targeting a convoy of Chinese engineers working on a power project in Sindh province.

The separatist Balochistan Liberation Army (BLA), which has in recent years carried out attacks on Chinese nationals involved in development projects in Pakistan, has said it carried out the attack.

In a statement released on Monday, the militant group said it had "targeted a high-level convoy of Chinese engineers and investors" arriving from Karachi airport.

A later statement from the group described it as a suicide attack, and named the perpetrator as Shah Fahad, part of a BLA suicide squad called Majeed Brigade.

The attack was carried out using a "vehicle-borne improvised explosive device", Reuters news agency quoted the BLA as saying.

The explosion happened around 23:00 local time (17:00 GMT) on Sunday.

Pakistan’s Prime Minister Shehbaz Sharif called the attack a "heinous act" and offered his condolences to the Chinese people.

"Pakistan stands committed to safeguarding our Chinese friends," he wrote on X.

The country's foreign ministry said it is "in close contact" with Chinese authorities and will "bring to justice those responsible for this cowardly attack".

"This act of terrorism is an attack not only on Pakistan, but also on the enduring friendship between Pakistan and China," the ministry said.

"This barbaric act will not go unpunished," it added.

The Chinese embassy said that the engineers were part of the Chinese-funded enterprise Port Qasim Power Generation Co Ltd, which aims to build two coal power plants at Port Qasim, near Karachi.

Thousands of Chinese workers are in Pakistan, many of them involved in creating an economic corridor between the two countries as part of Beijing’s multibillion dollar Belt and Road Initiative.

The Port Qasim plant is part of the corridor, along with a number of infrastructure and energy projects in Pakistan's Balochistan province, which has a rich supply of natural resources, including gas and minerals.

The BLA along with other ethnic Baloch groups has fought a long-running insurgency for a separate homeland.

It has regularly targeted Chinese nationals in the region, claiming ethnic Baloch residents were not receiving their share of wealth from foreign investment the province and natural resources extracted there.

The Chinese embassy on Monday reminded its citizens and Chinese enterprises in Pakistan to be vigilant and to "do their best to take safety precautions". The embassy added that it hoped Pakistan would thoroughly investigate the attack and "severely punish the murderer".

Security officials examine wreckage at the site of the explosion

The blast was reportedly heard in various areas around the city, with footage from local media showing thick smoke and cars set alight.

Pictures online show security officials and firefighters investigating the explosion site, with several vehicles charred by the blast.

A police surgeon, Dr Summaiya told Dawn news: "Ten injured persons, including one in critical condition, have been brought the Jinnah Postgraduate Medical Centre [JPMC]."

She added the injured included a police constable and a woman.

A statement posted on X from Sindh's Interior Minister's office said that a "tanker truck" had exploded on Airport Road. Roads leading to Jinnah International Airport were sealed off following the attack, but the airport is functioning as usual on Monday.

There has also been heightened security in Pakistan as it prepares to host the leaders' summit of the Shanghai Cooperation Organisation (SCO).

There have been multiple attacks on Chinese nationals in Pakistan in recent years. The BLA has claimed responsibility for several of them, including an attack in March on a Pakistani naval airbase near Gwadar port, another main feature of the China-Pakistan economic corridor.

In April 2022, the group killed three Chinese tutors and a Pakistani driver in a suicide bombing near Karachi University's Confucius Institute.

In November 2018, gunmen killed at least four people in an attack on the Chinese consulate in Karachi.
