A suicide bomber targeted a police station in Pakistan's capital, Islamabad, Monday evening, killing himself and one officer.
Officials say police tried to stop the bomber at a point before he detonated his explosives. It is not clear how many people were wounded in the attack.
Militants have staged a wave of attacks over the past few years in Pakistan, including several in the capital. The government has recently signed two separate peace deals with Islamist groups in the tribal regions near the border with Afghanistan.
The country marked its national holiday, Pakistan Day, on Monday. The holiday commemorates the 69th anniversary of the movement by Muslims on the Indian sub-continent to create a separate country.
