A curfew has been imposed in the northwest Pakistani city of Dera Ismail Khan after a massive jail break.

 

　　As many as 150 heavily-armed militants attacked a central jail over night, freeing the prisoners in a raid which has left at least 14-people dead.

 

　　Some 250 prisoners have managed to escape.

 

　　25 of them are described as "dangerous terrorists" by local authorities.

 

　　Local authorities say the attackers used machine guns and explosive devices in the assault.

 

　　"Last night terrorists attacked, they detonated improvised explosive devices at different places around the prison. 12 were big and nearly 200 smaller ones".

 

　　Security forces say the attackers were wearing police uniforms, and used megaphones to call out the names of specific prisoners.

 

　　So far only 9 of the prisoners who escaped have been recaptured.
