A roadside bomb in Kabul hit Afghan Vice President Amrullah Saleh on Wednesday morning, but he escaped unharmed, his spokesman was murdered after the attack and wounded more than 20 people, including some of his bodyguards.
There was no instant claim of responsibility for the attack, which comes just ahead of long-expected peace talks between the Taliban in Qatar’s capital of Doha and the Afghan government.
A former intelligence chief, Saleh has survived multiple assassination attempts, including one on his office last year that extinguished the life of 20 people.
A Health Ministry spokesman said, the explosion killed more than four people and wounded 16 people.
Officials and diplomats have warned that spiking violence is sapping trust needed for the success of talks aimed at terminating insurgency that began when the Taliban was expelled from power in Kabul by U.S.-back forces in late 2001.
