At least 20 police officers have been killed in a suicide bomb attack in Afghanistan, authorities have said.

The attack happened on Tuesday (17 February) in Pul-i-Alam, the capital of Logar, east of Kabul, AP reports.

Logar's provincial governor Din Mohammad Drwish said eight people were also injured in the blast.

No group has claimed responsibility for the casualties but the Taliban has been blamed for similar attacks.

Earlier on Tuesday, a bomb attached to a vehicle carrying a civilian exploded in Kabul – injuring one person whose identity has not been revealed. It was again unclear who instigated the crime.

In a separate incident, another suicide bomber recently blew himself up at the entrance of a police headquarters in the northern province of Kunduz – killing four members of the security forces.

Taliban militants killed six Afghan police officers and wounded eight others in two separate assaults in southern Afghanistan earlier this month.

The surge in Taliban attacks on Afghanistan security forces has increased since the withdrawal of foreign troops last year after 13 years of war.
