Syrian Observatory: Damascus Suburb Rocked by Bomb, 5 Killed

A bomb rocked the Damascus neighborhood of Qaboon during the night killing five people, the Syrian Observatory for Human Rights said on Tuesday.

The Britain-based group gave no further information on the deadly explosion but said powerful blasts were also heard overnight in several regions across the country, including central Hama and the coastal cities of Banias and Latakia.

On Monday, at least 54 people, including 31 soldiers were killed in the ongoing unrest that has shaken Syria since March last year, the watchdog said.

U.N. chief Ban Ki-moon warned on Monday that the search for peace in Syria was at a "pivotal moment" and expressed strong concerns of an all-out civil war, as a five-week-old truce was broken yet again.
