Gunmen have attacked an education department office in the eastern Afghan city of Jalalabad, holding out against security forces for about four hours before the assault ended with at least 10 people killed.
Officials say there were three attackers, two of whom detonated suicide-bomb vests, while the third was shot by security forces.
It was the third major attack in less than two weeks in Jalalabad, the main city of Nangarhar province, following a blast that killed a group of Sikhs on July 1 and a second that killed at least 12 people on Tuesday.
There was no immediate claim of responsibility for Wednesday's attack but both of the other assaults in the city this month were claimed by Islamic State, which is opposed to both the Western-backed government in Kabul and the Taliban.
The attack on the education department appeared to follow the pattern of previous attacks including an assault on an office of the Save the Children aid group in Jalalabad in January and another on the city accounts office in May.

On the other side of the country, in the western province of Farah, four people were killed and three wounded when their car set off a roadside bomb as they were travelling to a wedding, a provincial official said.
