A giant screen at the entrance of the Swiss resort of Montreux welcomes to this week’s Syria peace talks in Montreux and Geneva, Switzerland, Tuesday, Jan. 21, 2014. Russia and Iran on Tuesday criticized the U.N. chief’s decision to withdraw Tehran’s invitation to join the peace conference on Syria, as diplomats said a new report on Syrian regime atrocities underscored the urgent need to try to end the country’s brutal civil war.
