The Obama administration has summoned Syria's senior envoy in the U.S. to express outrage over a Syrian government offensive in the city of Homs.
The State Department said its top diplomat for the Mideast, Jeffrey Feltman, met Wednesday with Zuheir Jabbour, the highest ranking official at the Syrian Embassy in Washington.
A statement said Feltman expressed "outrage over the month-long campaign of brutality and indiscriminate shelling" in Homs. He told Zuheir the Syrian regime must end the violence, remove its military from cities and accept an Arab-proposed plan for a transition of power.
Syrian troops have shelled rebel-held areas of Homs for weeks. They appeared Wednesday to be mounting an operation to retake what has become a symbol of the uprising to oust President Bashar Assad.
