KABUL: A female suicide bomber blew herself up outside a local branch of Afghanistan's spy agency in the eastern city of Asadabad on Saturday, a spokesman for the Kunar provincial governor said.

The woman struck outside the local operations centre for the National Directorate of Security (NDS), said spokesman Wasifullah Wasifi.

“As a result of the explosion two guards of the operative directorate were wounded,” he added.

The attack comes a day after the Taliban launched a four-hour long assault on a US-run civilian-military base and NDS local branch in the southern city of Kandahar, the spiritual birthplace of the insurgent movement.

Around the same time as the explosion in eastern Kunar, another suicide bomber struck a convoy of foreign forces in the capital Kabul.
