During the 10-minute telephonic conversation, Sonowal briefed the Union Home Minister about the militant attack, the situation arising of the incident and the steps taken to nab the culprits.
"I am deeply anguished by the death of army soldiers in an attack in Tinsukia and pray for speedy recovery of the injured. We are monitoring the situation," Singh said.
Three jawans were killed and four others seriously injured in the ambush by a joint group of ULFA(I) and NSCN(K) militants at Pengeri in upper Assam's Tinsukia district today.
A group of about 15 militants attacked an army convoy early this morning and severely damaged two vehicles killing one jawan on the spot and seriously injuring six others, a defence spokesman told PTI.
Two of the injured succumbed to their injuries on way to the hospital, he said.
