Pakistan's Taliban warned on February 18 of more attacks against law enforcement officers, a day after four people were killed when a suicide squad stormed a police compound in Karachi. The police are often used on the front line of Pakistan's battle with the Taliban and are frequently a target of militants who accuse them of extrajudicial killings. In the evening on February 17, a Taliban suicide squad stormed the Karachi Police Office compound in the southern port city, prompting an hours-long gun battle that ended when two of the attackers were shot dead and a third blew himself up.
