After completing one of the tournament's greatest ever shocks when they cut Argentina down to size in their opener, the Saudis found Poland a tougher nut to crack.

Poland and other Western states have said the missile that landed in Przewodow, a village near the border with Ukraine, was a Ukrainian air defence missile that went astray in pursuit of a Russian missile.

But Nato chief says that Moscow, not Kyiv is ultimately to blame, for starting the war in the first place and launching the attack that triggered Ukraine's defences.

Poland is protected by Nato's commitment to collective defence but the alliance's response will likely be heavily influenced by whether the incident was accidental or intentional.

Nato member Poland had said a rocket killed two people in eastern Poland near Ukraine, and it summoned Russia's ambassador for an explanation after Russia denied it was responsible.

The explosion at a grain facility near the Ukrainian border came as Russia unleashed a wave of missiles targeting Ukrainian energy infrastructure, attacks that Kyiv said were the heaviest in nearly nine months of war.

The explosion, which firefighters said killed two people, raised concerns of Russia's war in Ukraine becoming a wider conflict.

The Polish foreign ministry says the rocket fell on Tuesday afternoon on Przewodow, a village in eastern Poland about 6km from the border with Ukraine, killing two.

Construction of the temporary 2.5m high and 3m deep barrier will start immediately, Defence Minister Mariusz Blaszczak says.

The man was jailed and faces a 25-year jail sentence for the killing.
