Ukraine war: Poland says missile deaths an unfortunate incident
Polish President Andrzej Duda has said there are no signs of an intentional attack after a missile strike killed two people on a farm near the western border with Ukraine.
Earlier, US President Joe Biden said it was "unlikely" the missile had been fired from Russia.
The two workers were killed as Ukraine came under fire from one of the biggest barrages of missile strikes of the war.
The Kremlin had insisted it had nothing to do with their deaths.
Poland said initially that the missile that had come down at Przewodow, 6km (4 miles) from the border, was Russian-made.
Accusing Western states of a hysterical reaction, Russian spokesman Dmitry Peskov said Warsaw should have immediately made clear the debris had come from Ukraine's S-300 air defences. read more
