Putin vows revenge for Russia air crash

President Vladimir Putin blamed terrorists for the air crash in Egypt that killed 224 people and vowed to step up military strikes in Syria to punish those who carried out "one of the bloodiest crimes" against Russians. "Not for the first time, Russia is confronted with barbaric terrorist crimes," Putin said in comments broadcast Tuesday. "We won't wipe the tears from our souls and hearts. This will remain with us forever. But it won't stop us from finding and punishing the perpetrators." Russia must know the names of all those involved in the crime, Putin said. "We will hunt them everywhere, wherever they're hiding. We'll find them anywhere in the world and we'll punish them." Russian air strikes in Syria must continue and be increased "so these criminals understand that retribution is inescapable," Putin told Defense Minister Sergei Shoigu at a meeting.
