New Delhi: US Vice President Joe Biden stated that it was “unlikely” that a missile that killed two people in NATO ally Poland was launched from Russia, but he did promise help for Poland’s probe into what it had referred to as a “Russian-made” missile.

In Indonesia on Wednesday morning, Biden called a “emergency” meeting of the leaders of the Group of Seven and NATO to discuss the attack that left two people dead in the eastern portion of Poland close to the Ukrainian border.

“There is preliminary information that contests that,” Biden told reporters when asked if the missile had been fired from Russia. “It is unlikely in the lines of the trajectory that it was fired from Russia, but we will see.”

The president called Polish President Andrzej Duda early on Wednesday to express his “sad sympathies” for the loss of life after being awakened overnight by staff with the news of the missile explosion while in Indonesia for the Group of 20 summit. On Twitter, Biden made the following promises: “reaffirmed the United States’ unshakable commitment to NATO,” and “full US support for and aid with Poland’s probe.”

It was “totally unanimity among the guys around the table,” according to Biden, who updated the allies on his meetings with Duda and NATO Secretary General Jens Stoltenberg. They also agreed to back Poland’s probe into the attack.

“I am going to make sure we figure out exactly what happened,” Biden said. “Then we are going to figure out our next step.”

The US president hosted the leaders of the G-7, which consists of Canada, France, Germany, Italy, Japan, the United Kingdom, and the European Union, as well as the president of the European Council and the prime ministers of NATO allies Spain and the Netherlands, at a large round table in a ballroom in his hotel.

The missile was recognised as being built in Russia in a statement from the Polish Foreign Ministry. Duda, the president of Poland, was more circumspect regarding its provenance, claiming that neither its maker nor its exact shooter were known to the authorities. Although he claimed it was “very likely” built in Russia, this is still being confirmed. If true, it would mark the first instance of a Russian weapon striking a NATO nation since the invasion of Ukraine.

The idea that an attack against one member is an attack on all members of the alliance is the cornerstone of NATO.
