Pakistani authorities say armed men attacked a Christian residential area near Warsak Dam in the suburbs of Peshawar early on September 2.
Lieutenant General Asim Bajwa said on Twitter that the attackers included at least four suicide bombers and that the military "promptly responded," killing all four attackers.
An RFE/RL correspondent said one civilian also appeared to be dead. There was a heavy exchange of fire between the militants and security forces, and the sound of firing and blasts and a helicopter hovering could be heard coming from the area at around 6 a.m. local time.
The incident occurred near where the Army Public School in Peshawar is located. That is the school where a Taliban attack in 2014 killed over 150 people, most of them schoolchildren.
