Police in Afghanistan say attackers have shot and killed an Afghan senator who briefly served as prime minister in the early 1990s.

Authorities say Abdul Saboor Farid was killed late Wednesday outside his home in the capital, Kabul.  Mr. Farid was Afghanistan's prime minister for one month in 1992 during the chaos of a civil war that followed the defeat of the Soviet army.  The motive for the senator's killing is not clear.

In another development, police say a remote-controlled roadside bomb tore through the side of an Afghan army bus Thursday in Kabul, killing the driver and wounding 29 people. 

Taleban militants claimed responsibility for the attack.

Meanwhile, the British defense ministry says a British soldier serving with the NATO-led coalition in Afghanistan was killed during fighting with militants in the south.

NATO has launched large-scale military operations in the region recently to pre-empt an expected Taleban offensive.
