Kabul's Deputy Governor Mahboobullah Mohebi was killed in a magnetic IED blast, Afghanistan officials have reported.
According to reports Mohebi, who was travelling with his secretary, died due to a sticky bomb attached to his car going off. Two guards were injured in the blast.
No militant group has made an immediate claim of responsibility for the blast. Last week an Afghan government prosecutor was shot dead in eastern Kabul while he was on his way to work.
