Overnight explosion rocks Damascus; Syrian government blames Israel

Syrian state media said it was from Israeli missiles; Israel had no comment.

— -- An large overnight explosion on Thursday rocked Syria's capital, the country's state media and opposition activists said.

The explosion occurred at a military installation near the Damascus airport, according to both SANA state TV and the Syrian Observatory for Human Rights, a U.K.-based monitoring organization with on the ground contacts in Syria.

"I don't want to go into the matter more or expand on it," he added, before saying that "the Prime Minister has said that every time that we receive intelligence of efforts to transfer advanced weapons to Hezbollah -- we will act. This incident is exactly in line with that policy."

The blasts were reported at 4 a.m. local time. While damage was reported, there were no immediate casualty reports.
