A car bomb apparently targeted at a convoy of vehicles belonging to an international organisation has exploded in Kabul on Friday, killing or wounding at least seven people.
There was no immediate claim of responsibility for the blast, which came a day after militant group Islamic State claimed a suicide attack outside a military training academy that killed at least six people.
"It was a suicide attack that targeted foreigners," said one security official, who spoke on condition of anonymity because he was not authorised to speak publicly.
He said four Kabul residents had been killed by the blast, which damaged the SUV-type vehicles in the convoy, and there were casualties among the foreigners.
The explosion, which sent a plume of white smoke into the sky, occurred on the busy Jalalabad road in the city's east, an area with several large security compounds which has seen repeated attacks over the years.
