KHOST, Jan 19: Bomb blasts killed two policemen and a teenager in Afghanistan on Monday, and wounded nearly 20 other people in fresh attacks.

A suicide attacker blew up a car packed with explosives near a US base for Nato’s International Security Assistance Force (Isaf) in the eastern town of Khost, US and Afghan officials said.

A 15-year-old boy was killed in the blast, said doctor Abdul Majeed from the town’s main hospital. Isaf said five children were among 12 Afghans treated for injuries.

A second suicide bomber had apparently planned to blow himself up in the crowd that gathered after the first blast, but detonated his explosives without causing casualties, the interior ministry said.

A policeman and civilian were also wounded when militants remotely detonated a roadside bomb next to a passing police vehicle in Khost, provincial police chief Abdul Qayoom Bakizoy told —AFP.
