Roadside bomb attack in Syria

Syrian state media said that a roadside bomb that blew up in Aleppo on Thursday, killing one officer and wounding at least 24 cadets and officers, was planted by what they described as terrorists, shortly after the start of a truce.

The broadcaster said it was an attempt to sabotage a U.N.-backed ceasefire that came began on Thursday.

The report raised the possibility troops may hit back.

There was no independent confirmation of the blast in Syria, where media access is severely restricted.

The Syrian news agency SANA blamed what it said was a "terrorist group" for a separate attack in the northern province of Idlib - a roadside bomb SANA says was targeting a vehicle belonging to the security forces.

The attack was reported in the hours following a dawn ceasefire brokered by U.N. peace envoy Kofi Annan who is trying to mediate an end to 13 months of fighting between Assad and his opponents, including the rebel Free Syrian Army.
