Syria's police have come out in force, again cracking down on protests, now targeting students in Aleppo.

Activists said security forces used batons to disperse a pro-democracy demonstration by 2,000 students on Wednesday at a university campus in Syria's second largest city.

Thousands of protesters have been detained and rights groups say around 800 killed, including at least 19 people since Wednesday.
