Russia has accused the U.S of seeking to prolong the war in Ukraine after President Biden said he would supply Kyiv with new long-range missiles.
Kremlin spokesman Dmitry Peskov said the U.S was “intentionally adding fuel to the fire” with the deliveries.
Separately, the German government has promised to send an air defence system to Ukraine.
Chancellor Olaf Scholz told MPs that the IRIS-T system was the most modern Germany possessed and would enable Ukraine to defend an entire city against Russian air attacks.
Russian Foreign Minister Sergei Lavrov hit out against the deliveries and said Mr Biden’s announcement increased the risk of a “third country” being dragged into the conflict.
The long-range missiles are to help Ukrainian troops strike enemy forces more precisely from a longer distance.
U.S had previously been unwilling to provide the weapons out of fear they could be used against targets in Russia, but the US says Kyiv has given assurances that this will not happen.
Today, Mr. Biden said the lethal aid would strengthen Kyiv’s negotiating position against Russia and make a diplomatic solution more likely.
