Gunmen in Afghanistan have killed a senator who served briefly as the country's prime minister 15 years ago.
Abdul Sabur Farid was shot outside his home in the capital, Kabul, on Wednesday night, officials said.
Mr Farid, a member of the upper house of Parliament, was the country's prime minister for a month in 1992. Police say no arrests have yet been made.
Violence has surged in Afghanistan in recent weeks. About 4,000 people were killed in the country last year.
On Thursday a roadside bomb hit an Afghan army bus in Kabul, killing the driver, and wounding 22 soldiers, officials say.
Police said Mr Farid, who was in his mid-50s, was shot dead by unknown assailants who had set up an ambush for him.
Witnesses heard three shots as Mr Farid left home to go to a mosque, reports said.
"I cannot believe that he was killed. The tyrants opened fire from a Toyota Corolla (car)," his son Tayad Farid told the Associated Press news agency.
Nafat Gul, also a senator, condemned the killing. "Afghanistan's government should be able to protect its lawmakers," he told AP.
Police said the motive for the killing was not known and they are investigating the shooting.
Mr Farid represented the northern province of Kapisa where he had earlier been a senior Mujahideen commander.
In July 1992 he served as prime minister for a few weeks when a bitter civil war erupted in Afghanistan.
