Afghanistan and Pakistan have pledged to work closely together on counter-terrorism, by boosting border security and co-operation on arresting terror suspects.
Pakistani Interior Minister Rehman Malik and his Afghan counterpart, Mohammad Hanif Atmar, held talks in Kabul Saturday.
Militants along the Afghan-Pakistani border have carried out attacks against international forces and civilians in both countries. Atmar said it is not important where the "terrorists" are from, but what both Afghanistan and Pakistan can do to stop them.
On Saturday, the Afghan defense ministry said a suicide bomber detonated his explosives-laden vehicle next to an Afghan army convoy in the Shah Joy district of Zabul province, killing at least three soldiers.
In Nangarhar province, two civilians and three militants were killed when local residents tried to stop militants from attacking an Afghan army officer.
A local official (Ahmad Zia Abdulzai) said residents detained 11 Taliban militants, including eight from neighboring Pakistan.
And the U.S. military said an F-15 fighter jet crashed in eastern Afghanistan early Saturday, killing the two crew members on board.
A military statement said the plane crash was not caused by "hostile fire." A local Afghan official (Mohammad Qasim Naziri) said the plane crashed in a remote area of Nawur district in Ghazni province. It said U.S. forces sealed off the area.
