A suicide attacker riding a motorcycle blew himself up inside Kabul’s heavily fortified diplomatic zone late on Tuesday evening killing at least three people and wounding 15, officials said

It was the first attack targeting the Afghan capital’s so-called “Green Zone” since a massive truck bomb ripped through the area on May 31, killing or wounding hundreds.

“Our initial information shows the suicide attacker was on a motorcycle. He made it through the first checkpoint but was stopped at the second checkpoint and detonated,” defence ministry spokesman Dawlat Waziri told AFP.

A health ministry official confirmed the casualty toll.

AFP reporters heard a loud explosion around 4pm just as workers would have been leaving their offices, followed by the sirens of emergency services.

Witnesses told AFP they saw multiple casualties being carried from the scene of the blast and driven away in ambulances.
