A car bomb attack in the Afghan capital Kabul has killed at least 10 people and injured 40 others, officials say.

The blast happened near a security checkpoint in a highly protected area close to embassies and government buildings.

Kabul has been gripped by a surge in violence since the US and the Taliban reached an agreement in principle to bring an end to the war. 

As part of the deal with the militants, the US would withdraw 5,400 troops from Afghanistan within 20 weeks, according to US top negotiator Zalmay Khalilzad.

The attack took place on a road near the Nato office and US embassy in the Kabul's heavily fortified Green Zone, and destroyed cars and nearby shops. The Taliban said they had targeted a convoy of foreign forces. 

On Monday, a truck bomb exploded close to a compound housing foreigners killing at least 16 people and injuring more than 100, an attack that was also claimed by the Taliban.
