VATICAN CITY - Pope Francis on Tuesday criticized countries which are arming the warring parties in Syria while speaking at the same time of peace.The pontiff did not name any countries. President Bashar Assad's government is receiving military and other help from Russia and Iran, while some opposition groups have the backing of Sunni Muslim regional powers and the West."While the people suffer, incredible quantities of money are being spent to supply weapons to fighters. And some of the countries supplying these arms are also among those that talk of peace," Francis said in a video message to a charity group holding a conference on Syria."How can you believe in someone who caresses you with the right hand and strikes you with the left hand?"
