SUKKARIYEH, Syria (AP) — A cross-border raid by U.S. special forces killed the al-Qaida-linked head of a Syrian network that smuggled fighters, weapons and cash into Iraq, an American counterterrorism official said Monday. Blood stained the earth in this border village as anguished Syrians buried relatives they said were killed in the U.S. helicopter attack Sunday. Some shouted anti-American slogans and carried banners reading “Down with Bush and the American enemy.” The operation targeted the home of Abu Ghadiyah, the nickname for the leader of a key cell of foreign fighters in Iraq.
