The Kremlin has made its first comment on the situation in Poland…but only to say it won’t comment.

“We wouldn’t like to comment on this,” says Kremlin spokesman Dmitry Peskov on his daily conference call with journalists.

“This is not for us to do so. It’s a matter for the [Russian] defence ministry.”

When asked about the accusations being levelled at Moscow, Peskov replies: “The leadership of the EU and Nato accuse Russia of provocations on a daily basis, usually without backing this up.”

Early this morning, a number of flights which had been due to land at Warsaw Chopin airport from various locations - including Gran Canaria, Toyko and Paris - were diverted.

Warsaw Chopin is Poland’s biggest airport. Now there are numerous delays showing on the airport’s arrivals board. For example, a Wizz flight from Copenhagen which had been due to arrive at 10:10 local time, is now due at 12:01.

A few cancellations are showing up too, but mostly delays. It’s a similar picture with departures - widespread delays, a few cancellations. For airlines, any substantial delays can have a knock-on impact on the rest of the day’s operations.

West's response not enough to make Putin fear sending drones to Polandpublished at 11:28 BST 10 September

This is yet another example of the Western policy of escalation management failing.

For years, the West's response to Russian attacks in Ukraine has been moderated by fears of provoking Moscow into doing something even more aggressive and violent.

These fears - as well as financial constraints - have stopped Ukraine's allies from providing it with more and better weapons, let alone deploying boots on the ground.

But the Kremlin is free from such concerns. It has put Russia's economy on a war footing, and is unafraid to escalate by stepping up air attacks on Ukraine, targeting civilians, or involving North Korean troops.

The response we have seen from the West so far is not enough to make Putin fear consequences should he decide to send drones into Poland.

Donald Tusk says Poland is at its closest to open conflict than at any time since World War Two.

"I have no reason to claim we're on the brink of war, but a line has been crossed, and it's incomparably more dangerous than before," the Polish prime minsters tells parliament.

"This situation brings us the closest we have been to open conflict since World War Two".

Authorities in Poland have found seven drones and the remains of an unidentified object in sites across the country following the multiple incursions of Polish airspace overnight, an interior ministry spokeswoman says.

Karolina Galecka tells a news conference that five of the drones and the remains of the unidentified object were found in different locations across Lublin province, in eastern Poland, which borders Belarus and Ukraine.

She says the remaining two drones were discovered in central and northern Poland, much further from the borders:

• One was discovered in a field in Mniszków, in Łódź province in central Poland, about 250 km (155 miles) from the Belarusian border
• Another was discovered near the city of Elbląg in northern Poland

French President Emmanuel Macron describes the incursion as "simply unacceptable", adding that he will soon meet Nato Secretary General Mark Rutte.

The European Council's president, Antonio Costa, says Europe is increasing investment in its defence following Russia's "reckless" actions. "Peace and security in Europe cannot be taken for granted," he adds

Viktor Orbán, Hungary's Prime Minster, calls the air incursion "unacceptable". Orbán, along with Slovakia’s prime minister Robert Fico, has kept close ties to the Kremlin following its full-scale invasion of Ukraine in 2022.

Petr Fiala, the Czech prime minster, says it's "hard to believe" that last night's Russian drone attack on Poland was a coincidence. He accuses Russia of "systematically probing to see how far it can go".

Alexander Stubb, Finland's president, claims that Russia "seeks escalation" and "carries responsibility" for violating Poland's air space.

Latvian President Edgars Rinkēvičs also expresses his full support and solidarity to Ukraine, emphasising that allies "must be working together".

Update 1 October: This post has been amended to mention that along with Viktor Orbán, Slovakian Prime Minister Robert Fico also has close ties with Russia.

UK Prime Minister Keir Starmer has condemned "barbaric attack on Ukraine and the egregious and unprecedented violation of Polish and Nato airspace by Russian drones".

“This was an extremely reckless move by Russia and only serves to remind us of President Putin’s blatant disregard for peace, and the constant bombardment innocent Ukrainians face every day," he says in a statement.

He has been in touch with the Polish prime minister to show support, Starmer adds.

“We will continue to ramp up the pressure on Putin until there is a just and lasting peace.”

Meanwhile in London, UK Defence Secretary John Healey will host his German, Polish, French, Italian and Ukrainian counterparts - members of the European Group of Five (E5) - for talks.

We're expecting them to host a joint press conference at 14:00 BST.

In another update from Ukrainian President Volodymyr Zelensky, the leader says the first crossing of the border into Poland by a Russian drone occurred at 00:50 local time (23:50 BST).

He writes on X that "at least two Russian drones that entered Polish territory during the night used Belarusian airspace".

This "may be greater than the previously announced figure", he says.

• As a reminder, Polish Prime Minister Donald Tusk has said the Polish military recorded 19 drone incursions in the country’s airspace overnight

Drones were "apparently" approaching targets in Poland as well as in Ukraine, he adds.

He says updated data suggests there were at least two dozen Russian drones that could have entered Polish airspace. Ukraine is working on verifying this, he adds.

Writing on X, Polish Prime Minister Donald Tusk said: “My thanks and congratulations to the Polish Operational Command and our Nato pilots for shooting down Russian drones over Poland.

"Actions speak louder than words.”

The security of Polish airspace has been stabilised and the threat level is back to normal, the operational command of its armed forces has said.

It says its radar and ground-based air defence systems have also returned to their standard activities.

The statement adds that it is continuing to monitor the situation in Ukraine - where it's "observing further strikes" by Russia - and remains in "constant readiness" to protect Poland's airspace.

Images are coming into us now from the Polish village of Wyryki, in the south-eastern Lublin province - one of three classed as vulnerable overnight.

Pictures appear to show a house damaged by the drones, in addition to a significant emergency service and military presence.

The BBC has not independently verified the locations or damage from any drones.

Ukrainian officials have no doubt that this was a deliberate move by Russia and they’re calling for a strong response.

Writing on X, President Zelensky warns that Moscow always escalates and “tests the limits of the possible”.

He says “at least eight” Iranian-built Shahed attack drones were “aimed in the direction of Poland". Poland has not yet disclosed details.

Zelensky calls it “an extremely dangerous precedent for Europe”.

The Russian drones that entered Poland were part of the latest major aerial attack on Ukraine.

In total, the air force here reports that more than 400 drones and 42 cruise missiles were launched.

The attack began just before midnight and here in Kyiv lasted throughout the night.

First we heard the air defences working, shooting down drones, then warnings of missiles across the country.

Zelensky says in Khmelnytskyi region in western Ukraine, a sewing workshop was hit and three people were injured. We’re still waiting for more details.

Poland is one of 32 members of the security alliance Nato (the North Atlantic Treaty Organisation).

One of its core principles is that an attack against one or more members will be considered an attack against all - known as Article 5.

All member states - including the US and the UK - restated their "ironclad commitment to collective defence" at the Nato summit in June.

Nato doesn't have its own army, but member states can take collective military action in response to international crises.

It was formed in 1949 with the primary aim of blocking the Soviet Union from expanding in Europe.

An adviser to Ukrainian President Volodymyr Zelensky - Mykhailo Podolyak - has posted this map on social media, external, which he says shows Russian drones over Ukraine last night. Some of the drones are shown to be entering Poland.

The map itself is not from an official source. It comes from a Telegram channel run by volunteers that tracks and warns Ukrainians about possible incoming aerial attacks.

"Russia deliberately, thoughtfully, and with specific intentions attacked Poland with drones," Podolyak says in the social media post.

Russia is yet to comment.

Russia's temporary chargé d'affaires - the chief of the embassy's mission in Poland - rejects claims that Russian drones entered Polish airspace.

"We believe that the claims are groundless. There has been no evidence that these drones are of Russian provenance," Andrey Ordash tells Russian state news agency RIA Novosti.

He also tells the agency that he has been summoned to the Polish foreign ministry.

Speaking to MPs in parliament, Polish Prime Minister Donald Tusk says: “There is no doubt that this provocation is incomparably more dangerous from Poland’s point of view than the previous ones.”

Tusk says Poland had requested invoking Article 4 of the Nato treaty, which allows member countries to raise an issue to the North Atlantic Council (Nato’s main political decision-making body).

Consultations are then held to determine whether the territorial integrity, political independence or security of a member country has been threatened.

Tusk says he expects greater support during those consultations.

“This is not just a war for Ukrainians. This is a confrontation that Russia has declared against the entire free world,” he said.

Polish Prime Minister Donald Tusk says the Polish military recorded 19 drone incursions in the country’s airspace overnight.

Speaking to the Polish parliament, Tusk says three - or perhaps four - drones were shot down by Polish and Nato aircraft that were scrambled to deal with the threat.

Tusk says a significant number of the drones flew into the country from Belarus. The last drone to be shot down was at 06:45 local time (05.45 BST), he says.

We've just received the image below from Reuters news agency, which it says shows parts of a damaged drone shot down by Polish authorities lying at a site near Zamosc, south-east Poland.

The BBC has not independently verified how many drones were downed or the locations of any that fell.

There's been complete silence so far from Russian officials.

But Russian state TV is quoting unnamed Polish members of parliament as saying this looks like a Ukrainian false-flag operation.
