(ANSA-AFP) - WARSAW, NOV 16 - Poland put its military on high alert Tuesday after what the country's president said was "most probably" a strike by a Russian-made missile. Western leaders held an "emergency roundtable" on Wednesday on the sidelines of the G20 summit in Indonesia, where they urged against jumping to any conclusions about the origins of the strike. Warsaw said the missile had killed two people in the southeastern village of Przewodow, near the border with Ukraine, but did not have conclusive evidence of who fired it. US President Joe Biden said it was "unlikely" the missile had been fired from Russia, while France urged "utmost caution" in identifying who was behind the blast. Moscow's ambassador has been summoned to provide "immediate detailed explanations" and the military had been put on heightened alert after an emergency national security council meeting, Polish authorities said.
