The United States on Wednesday condemned recent violence in Yemen, where two soldiers were killed and 14 others were injured this week when a bomb planted under a military bus exploded in the Yemeni capital, Sanaa. "We condemn recent violence and ongoing sectarian clashes in Yemen," State Department spokeswoman Jennifer Psaki said during the daily press briefing. "We support efforts to negotiate a lasting ceasefire and call on all parties to refrain from inflaming sectarian tensions or inciting violence at this critical moment in Yemen's political transition," Psaki added.
