Russia warns on arms supply

At least 12 killed in latest fighting and Merkel admits she cannot guarantee a cease-fire deal

Russia warned on Tuesday that Washington's plans to supply Kiev with arms would further destabilize the situation in Ukraine.

"Russia is truly interested in solving the crisis. All other plans to increase sanctions, supply arms and so on, are aimed at destabilizing the situation in Ukraine," said Kremlin spokesman Dmitry Peskov when he was commenting on a statement made by US President Barack Obama.
