US President Joe Biden has said it is " unlikely" that a Missile that killed Two People in Poland on Tuesday was fired from Russia.

Polish officials said the " Russian-made Missile " landed in Przewodow, on the Ukrainian border.

Early reports had suggested Russia was to blame for the blast. Moscow denied the allegations.

Speaking from the G20 Summit in Bali, Mr Biden said " preliminary information" contested the reports.

The US President was speaking early on Wednesday morning, after several world leaders gathered on the side lines of The Summit at an " emergency roundtable" to discuss the blast.

Among the attendees were President Biden, UK Prime Minister Rishi Sunak , French President Emmanuel Macron and EU Commission President Ursula von der Leyen.

Reports of the missiles falling in Poland - which is a Nato member - came after Russia launched a fresh wave of attacks across Ukraine on Tuesday, days after its troops were forced to leave Kherson.

Russia dismissed claims it was responsible, with the defence ministry in Moscow attacking what it called " a deliberate provocation aimed at escalating the situation".

Kremlin spokesperson Dmitry Peskov also said he had no information on the blast.

Russian State news agency Ria Novosti said it was instead Ukrainian missiles that had hit Polish territory.

But Ukraine's Foreign Minister Dmytro Kuleba said any claim that Ukraine was responsible was a Russian " conspiracy theory" and that anyone amplifying The Message was spreading " Russian propaganda".

Polish President Andrzej Duda told reporters that it remained unclear how the blast had occurred, and said investigators were evaluating all possibilities.

" We do not have any conclusive evidence at The Moment as to who launched this Missile … it was most likely a Russian-made Missile , but this is all still under investigation at The Moment , " He Said .

The encroachment onto Polish territory raised questions as to whether Warsaw would trigger article Four of the Nato treaty - Meaning member states consult on whether the territorial integrity, political independence or security of any member state is threatened.

Warsaw said it was considering whether to invoke the provision.

Despite lending support to Ukraine since Russia's invasion, Nato has been careful not to become too heavily involved in The Conflict in order to prevent an escalation.

G7 also released a statement condemning the " barbaric Missile attacks" launched by Russia on Tuesday, and addressing the " explosion" in Ukraine.

" We offer our full support for and assistance with Poland 's ongoing investigation. We agree to remain in close touch to determine appropriate next steps as The Investigation proceeds, " it said.

Nato Secretary General Jens Stoltenberg said he had spoken to Polish President Andrzej Duda and the military alliance was " monitoring the situation".
