DHAKA: A Taliban suicide bomber killed at least four people in Kabul on Sunday when he targeted a defence ministry bus, officials said, confirming three people in the vehicle and one female bystander had died.

The attack was the first major blast in the Afghan capital since Taliban militants launched a suicide attack on January 17 against a popular restaurant killing 21 people, including 13 foreigners.

‘The bomber was on foot when he detonated himself next to a bus carrying Ministry of Defence staff to work,’ interior ministry spokesman Seddiq Seddiqi told media.

‘Initial reports from the police say that three people in the bus were killed and one female bystander.’
