Kerry Calls for War Crimes Probe Into Russian Activity in Syria by VOA News U.S. Secretary of State John Kerry is calling for a war crimes investigation of Russia and Syria. He made the comment in a meeting in Washington with visiting French Foreign Minister Jean-Marc Ayrault Friday. Following an attack on a Syrian hospital Thursday night which left 20 dead and 100 wounded, Kerry said that people must be held accountable for the violence ravaging the country. "Russia and the regime owe the world more than an explanation about why they keep hitting hospitals, and medical facilities, and women and children," he said, adding that these acts "beg for an appropriate investigation of war crimes." WATCH: Kerry on hospital bombing in Syria An agreement between Kerry and Russian Foreign Minister Sergei Lavrov last month would have created a new counterterrorism alliance in Syria, had fighting stopped for a week - long enough for humanitarian aid to reach affected areas. Neither condition was met, and airstrikes have continued. Kerry ended bilateral discussions with Russia on their military partnership earlier this week. "They are beyond the accidental now, way beyond, years beyond the accidental," Kerry said. "This is a targeted strategy to terrorize civilians and to kill anybody and everybody who is in the way of their military objectives." As many as half a million people have been killed in Syria since the beginning of the war in 2011. The United Nations' special envoy for Syria, Staffan de Mistura, said Thursday that eastern Aleppo could be "totally destroyed" by the end of the year due to the "cruel, constant" military activities in the city. WATCH: De Mistura statement on Syria Russian Defense Ministry spokesman Major General Igor Konashenkov told journalists in Moscow this week that any airstrike or missile strike against Syrian government-controlled territory would present a "clear threat" to Russian service personnel present in Syria.
