KABUL, Afghanistan — At least four people were killed when a suicide bomber on a motorbike attacked a vehicle carrying members of the security forces on Wednesday in the capital Kabul, security officials said.
Sediq Sediqqi, spokesman for the Afghan interior minister, said Wednesday that 13 others were wounded in the attack.
No group has yet claimed responsibility.
A security official, who spoke on condition of anonymity because was not authorized to speak with the media, said the bomber attacked a mini-bus carrying members of an agency that provides protection for high-ranking government officials — similar to the U.S. Secret Service.
This is the second attack this year against the agency; in April, a coordinated Taliban attack using a suicide truck bomb and gunmen killed 64 people at the agency’s main compound.
