At least two policemen have been killed and two others injured in a suicide attack at a police checkpoint in Afghanistan's south eastern province of Paktita.

Abdul Rahman, who coordinates security in Paktika province, said two policemen and two civilians died in the attack Sunday in Yahya Khel district near Afghanistan's eastern border with Pakistan.

After the attack, gunmen fired bullets at the police headquarters from two or three directions, but the gunfire ended after 15 minutes and no other casualties were reported.

In a separate incident, two suicide bombers were killed by Afghan police early on Sunday in Qalat, the capital of southern Zabul province, the Interior Ministry said in a statement. Their explosives were not detonated.
