At least four people were killed when militants detonated bombs and stormed a government building today in the eastern Afghan city of Jalalabad, officials said.
"Security forces are in the area chasing and fighting them," he said.
Four bodies and about 20 wounded people had been brought to Jalalabad hospitals so far, said Dr Najibullah Kamawal, director of the city's health department.
There was no immediate claim of responsibility for the attack.
It was the latest deadly violence to strike Afghanistan as militant groups step up attacks and US-backed Afghan forces intensify air strikes and ground offensives.
