UN thinks al Qaeda was behind Syria blasts

United Nations Secretary-General Ban Ki-Moon says al-Qaeda was probably behind a terrorist attack in Syria last week that killed 55 people.

UN Secretary-General Ban Ki-moon says he believes that, "alarmingly and surprisingly", al-Qaeda must have been behind the big terrorist attack in Syria last week.

The twin suicide car bombings outside a military intelligence building in Damascus on May 10 had the al-Qaeda-style tactics seen in neighbouring Iraq.

About 55 people died and dozens were injured in the blasts.

Ban said on Thursday that al-Qaeda's involvement in the region "has created very serious problems".

He noted there have also been two attacks against unarmed UN monitors trying to reduce the Syrian violence that began more than a year ago with a popular uprising against President Bashar al-Assad.

Ban's comments were made to more than 2,500 students attending the annual Model UN Conference.
