Kabul, Oct 1 (IANS): At least six civilians were injured Wednesday in a bomb blast which targeted a police van in Afghanistan's Kunduz city.

Earlier, two suicide bombings rocked capital Kabul, killing nine people - seven army personnel and two suicide bombers - and injuring 21 others, Xinhua reported.

"An explosive device planted on a police van exploded next to a local bank in Kunduz city," an official said.

Taliban has claimed responsibility for the twin bombings in Kabul.

The attacks came a day after the country and the US inked a Bilateral Security Agreement to allow limited number of troops to remain in Afghanistan after the 2014 pullout of NATO-led troops in the country.

According to a statement, Taliban has slammed the signing of the agreement and has vowed to continue war till the eviction of all foreign forces from the country.

"The new rulers of Arg (presidential palace), by signing security agreement with America, betrayed the religion, the nation, people and the history of the country," the statement said.

"Inking such agreements will remain in paper and cannot affect the Jihad or holy war against foreigners," the statement added.
