Defense Minister Tomasz Siemoniak says Poland will not send lethal weapons to Ukraine but says there is little optimism in the west about the outcome of peace negotiations.

In interviews for Polish media Tuesday, Siemoniak said Poland has supplied the military in neighboring Ukraine with some 17 million zlotys (4 million euros, $4.6 million) worth of food rations, clothing and blankets and was preparing another such shipment. He told Gazeta Wyborcza daily that sending tanks, missiles or other heavy weaponry was "out of the question."

He says that given the "low credibility" of Russia, there was little optimism about the peace talks scheduled Wednesday involving Ukraine, Russia, Germany and France.
