The warning came hours after Syrian Foreign Ministry spokesman Jihad Makdessi criticized France, saying its growing support for the opposition does nothing but undermine the mission of the new U.N. envoy tasked with brokering a diplomatic solution to the conflict.
France, Syria's one-time colonial ruler, has been one of the most outspoken Western critics of the Assad regime, and announced earlier this month that it has begun sending direct aid and money to five rebel-held Syrian cities as part of its intensified efforts to weaken Assad. It was the first such move by a Western power amid mounting calls for the international community to do more to prevent bloodshed.
Makdessi said France suffers from "schizophrenia" in its approach to the country's conflict.
"On the one hand, it supports Brahimi's mission, while at the same time it makes statements demonstrating that it supports the militarization of the crisis in Syria," Makdessi told The Associated Press.
French officials have acknowledged providing communications and other non-lethal equipment to Syrian rebel forces, but say they won't provide weapons without international agreement. France played a leading role in the international campaign against Libya's dictator Moammar Gadhafi last year.
Diplomatic efforts to solve the seemingly intractable conflict have failed so far. A peace plan by former U.N. Secretary-General Kofi Annan never got off the ground and Annan quit his post as special U.N. envoy. He was replaced on Sept. 1 by Lakhdar Brahimi, a 78-year-old former Algerian foreign minister.
