CAIRO: Egyptian authorities say a drive-by shooting has killed three policemen during a rally by Islamist students overnight in Cairo.
The Interior Ministry says about 250 students from Al-Azhar University took to the streets late Monday night to show their support for the country's ousted President Mohammad Morsi, who hails from the Muslim Brotherhood.
The ministry says that as riot police tried to stop the demonstration, gunmen from a speeding car opened fire, killing three policemen and wounding nine.
Meanwhile, the state MENA news agency says suspected militants blew up a natural gas pipeline in the restive Sinai Peninsula late Monday.
Scores of similar militant strikes on pipelines have proliferated in recent years.
A Sinai-based Al-Qaeda-inspired group, Ansar Beit al-Maqdis, has claimed responsibility for several such bombings.
