At least four university students have been killed as security forces and soldiers raided student accommodation in Syria's second city, Aleppo.
Live ammunition was reportedly used to disperse an anti-government protest outside dormitories adjacent to Aleppo University's campus late yesterday.
As many as 200 students are thought to have been arrested during the raid.
The university has announced it is suspending all classes for the rest of the current academic year.
Aleppo has so far not experienced the violence and large-scale protests seen in other cities during the uprising.
The overnight crackdown was launched despite the Syrian government saying it was abiding by the terms of the peace plan negotiated by the UN and Arab League envoy, Kofi Annan, which includes a ceasefire and a commitment to allow peaceful protests.
