A roadside bomb in eastern Kabul has killed two employees of the presidential palace.
The explosion reportedly struck a minivan carrying seven staffers of the palace's media office on July 15.
The blast killed two passengers and also wounded five people, including the driver.
Kabul police say it was a remotely detonated device planted along the midsection of a main road.
No one immediately claimed responsibility for the attack.
Such attacks have escalated as the Taliban intensifies its campaign ahead of the withdrawal of U.S.-led foreign forces by the end of 2014.
