The Nato chief Jens Stoltenberg says the blast in Poland late on Tuesday was likely to have been caused by Ukraine's air defence systems
He echoed the words of Poland's President Duda, who also said there was no sign that the missile hit was part of an intentional attack

US President Joe Biden has also said it was "unlikely" that the missile was fired from Russia
The American reaction earned rare praise from Russia - with a Kremlin spokesman describing it as "restrained and professional"

Image source, ReutersCambodia's Prime Minister Hun Sen has cancelled his scheduled meetings at the G20, after he tested positive for Covid.
The current head of the Association of Southeast Asian Nations (ASEAN), Hun Sen had tested positive before he had held any meetings.
He had been due to meet Chinese leader Xi Jinping and French President Emmanuel Macron, among others.
He had earlier hosted an Asean summit that ended on Sunday in Cambodia, and he met US leader Joe Biden on Saturday, external.
Most nations taking part in the G20 summit are likely to issue a statement denouncing Russia's war against Ukraine, according to a briefing by a US official reported by news agency AFP.
The official said "most members [would likely make clear] that they see Russia's war in Ukraine as the root source of immense economic and humanitarian suffering in the world".
Russia is currently being represented at the G20 by its Foreign Minister Sergei Lavrov, after President Vladimir Putin said he would not be attending.
UK PM Rishi Sunak had earlier promised to "call out Putin's regime" at the meeting, saying that it would not be "business as usual".
The summit will also see leaders skip one of the diplomatic niceties of these gatherings this time, a group photograph known as the family photo - the other leaders don't want to be pictured alongside Lavrov.

Good morning and welcome back to our coverage of the G20 summit that's due to kick off on the Indonesian island of Bali today.
It comes just hours after US President Joe Biden met with Chinese President Xi Jinping - the first in-person meeting between the duo since Mr Biden took office.
As the summit opens, we're expecting issues like food security and debt relief to be widely discussed. We're also likely to see most member countries come together to condemn the destabilising effects of Russia's war in Ukraine.
Stick with us as we bring you the latest updates.
Image source, ReutersThanks for joining our live coverage of events in Indonesia - we'll be pausing this page soon.
Here's a quick look back at what's been happening on Monday.
During their meeting in Bali, ahead of the G20 meeting, the presidents of US and China said they want to "find the right direction" for their countries' relationship, and to "manage our differences".
US President Joe Biden said they should "prevent competition from becoming anything ever to near conflict".
Statesmen should "know how to get along with other countries and the wider world," said China's President Xi Jinping.
Image source, ReutersAlthough some high-profile meetings have already taken place today, the annual G20 summit is due to begin officially on Tuesday.
The G20, or Group of Twenty, is a club of countries which meets to discuss plans for the global economy. Between them, G20 countries account for 85% of the world's economic output and 75% of world trade, external. They contain two-thirds of the global population.
Every year, a different G20 member state takes over the presidency and sets the agenda for meetings.
As 2022 president, Indonesia wants the Bali summit to concentrate on global health measures and economic recovery following the coronavirus pandemic. It also wants to promote the adoption of sustainable energy.
However, this year tensions over the Ukraine war could hamper discussions.
Russia's President Putin won't be in attendance, and will be represented by his foreign minister, Sergei Lavrov.

Image source, ReutersInternational relations expert Ian Chong - who is with the National University of Singapore - feels the overall tone of President Joe Biden's meeting with Xi Jinping was positive.
There is a recognition that there is common ground between the two countries - including on food security, climate and not wanting nuclear war - added to the fact they are willing to talk, which is also a plus.
But Chong says there needs to be some caution as China and US relations have starts and stops.
At last year's UN climate summit COP26, for example, there seemed to be some mutual understanding between the two sides, but relations then took a turn for the worse.
So we have to see how things play out in the next few months, Chong says.
G20: US and China will work in lockstep with our allies and partners - Biden
If you missed Biden's press conference following his first meeting with Xi in Bali on Monday, here are the key points he said:
While America's President Biden was speaking, more lines emerged from the Chinese side - with state media giving further details of what President Xi said during the meeting of the two leaders.
The Chinese leader is said to be "highly concerned" about the situation in Ukraine following months of fighting.
China has previously called for restraint during the ongoing war there, but has stopped short of condemning the invasion by Russia - which is an important trading partner.
Just before Biden walks off, he answers one more question shouted out from the press pack on abortion rights.
The president says he doesn't think he will have the votes necessary to pass a law on abortion access - "unless something unusual happens in the House [of Representatives]".
Image source, ReutersBiden is next quizzed on North Korea and the country's reported plans for a new nuclear weapons test. He's asked whether China has the ability to talk Pyongyang out of any such test.
"It's difficult to say I'm certain that China can control North Korea," Biden says. But he says China has an "obligation to attempt" to ward off an nuclear test.
In the event of any test, the US would "take certain actions that would be more defensive", he says. He clarifies that these actions would not be "directed against China", but would instead be designed to send a message to North Korea.
US president later says, "I mean what I say and I say what I mean." He stresses the importance of avoid any "misunderstanding" over the intentions of the US and China.
Image source, ReutersTurning to a third question, Biden hails Ukraine's recent recapture of the city of Kherson from Russian control.
He describes it as a "significant victory".
"I can do nothing but applaud the courage, determination and capacity of the Ukrainian people," Biden says.
"You are going to see things slow down a bit in the winter months, but I am confident Russia will not occupy or defend Ukraine as they intended from the beginning."
Image source, ReutersBiden is asked whether the Chinese president appears more confrontational or more willing to compromise nowadays.
Biden responds that he found Xi Jinping "the way he's always been - direct and straightforward".
He adds that they were "very blunt with one another", and says "yes" in response to the question of whether Xi appears willing to offer compromises on certain issues.
The first question asked by a reporter is whether Biden believes that a new Cold War with China can be avoided - specifically on the issue of Taiwan - and whether he believes China is preparing to invade Taiwan. Biden is also asked whether he issued any particular warnings to China.
The US president replies: "I absolutely believe there will not be a new Cold War... I do not think there is any imminent attempt on the part of China to invade Taiwan." Biden also says that he has made it clear that the US policy towards Taiwan has not changed at all and that the US wants to see issues "peacefully resolved".
"I am convinced [Xi Jinping] understood exactly what I was saying."
Biden adds that the US is the best positioned country in the world to deal with economic and political changes and that he and Xi Jinping agreed their cabinet members would meet to discuss many of the issues that were discussed today.
Image source, ReutersNext, Biden speaks of what's on the agenda at the G20 summit of major economies.
He promises world leaders will be "tackling the very issues that matter to people's lives", including what he calls "the suffering" that has been unleashed by Russia's invasion of Ukraine - for example food insecurity.
More from President Joe Biden who reflects on his meeting with China leader Xi Jinping.
He insisted that the America's 'One China' policy has not changed and both are committed to keeping peace with Taiwan.
President Biden said the two countries would agree work together to solve global challenges and they also discussed Russia's threat against Ukraine.
He re-emphasised both countries' commitment to opposing nuclear warfare.

Image source, EVNPresident Joe Biden begins by speaking of the importance of using the upcoming G20 summit to bring together a "broad coalition" against a range of "great global challenges" including climate change.
Of his talks with Chinese President Xi Jinping, he says they had an "open and honest" conversation. He reiterates that they will "compete vigorously" but that he's not looking for "conflict".

Chinese state media has been reporting its own version of the talks between Presidents Xi and Biden.
The Chinese leader is said to have warned his opposite number against crossing a "red line" on Taiwan.
The island is a self-governing democracy - but is regarded by Beijing as a breakaway province which is one day destined to be reunited with the Chinese mainland.
The US has tried to walk a tightrope over the subject. President Biden has previously vowed to defend Taiwan if it's invaded - although such comments were walked back by the White House.
