MOSUL, Iraq - Thirty-five prisoners facing terrorism charges escaped through a sewage pipe from a temporary jail in Iraq's restive northern city of Mosul on Thursday, police and security officials said.
Police recaptured 21 of the escapees and imposed a curfew on the city as they looked for the rest, officials said.
Mosul, an al-Qaida stronghold located 390 km (240 miles) north of Baghdad in the troubled province of Nineveh, has seen a number of big prison breaks. Last year 23 prisoners convicted on terrorism charges escaped from the city's Ghazlani prison.
In 2007, dozens of al-Qaida-led militants stormed Badoush prison just outside Mosul and freed up to 140 prisoners. In December 2006, a nephew of Iraqi dictator Saddam Hussein escaped the same prison.
