Kabul , Afghanistan ( CNN ) -- A senior Afghan intelligence official was killed Thursday when a bomb exploded in the country 's northern Kunduz province , according to a provincial council chief . Payenda Khan -- who headed up a district in Kunduz for the National Directorate of Security -- was killed , and three children were injured in the blast , said Mahbobullah Mahbob . Khan was killed in the Afghan district of Bander Khanabad , and the Taliban have claimed responsibility for the attack . His death is latest in a series of high-level officials who have recently been killed across the country . The most high-profile strike occurred in July , when the Taliban also claimed responsibility for the death of the president 's half-brother , Ahmed Wali Karzai . The Kandahar provincial council chief was considered an influential power-broker and key presidential ally in the country 's southern provinces . Last week , militants stormed the compound of the governor of Afghanistan 's Uruzgan province . A least 19 people were killed and 37 wounded , including three police officers , in that attack . The governor , Muhammad Omar Shirzad , managed to escape after being surrounded by security guards while a gun battle raged for several hours . Elsewhere Thursday , two NATO service members were killed in eastern Afghanistan , according to an International Security Assistance Force statement . One soldier was killed when a man wearing an Afghan National Police uniform turned his weapon against the service member . The second person died from a separate insurgent attack , NATO reported . Meanwhile , coalition forces say they captured a senior Haqqani leader , responsible for more than 250 fighters , in the southeastern province of Paktiya . The Haqqani network is an insurgent group loosely affiliated with the Taliban , and is believed to operate out of Pakistan 's frontier territories . Last month , coalition forces reported a day-long fire fight in a `` known Haqqani network '' area in southeastern Afghanistan that left at least 50 alleged insurgents dead . CNN 's Matiullah Mati contributed to this report .
