At least two persons were killed and five persons were injured when militants opened fire in Assam's Tinsukia district.
"The incident occurred at about 8 p.m. Combing operations are on. Senior officials are on the spot," Assam DGP Mukesh Sahay told The Hindu.
He said that ULFA (Independent) may be behind the incident. The area where the incident occurred has high presence of Army and security forces.
The incident comes a week after NDFB (S) militants opened fire on Balajan Tinali market in the State's Kokrajhar district, killing 14 people.
There has been a general alert of possible terrorist attack ahead of Independence day.
PTI adds from Guwahati:
A group of five armed militants of the anti-talk ULFA faction came to the house of Arvind Shah, a small trader, of the village under Philobari police station, and opened fire at some people sitting outside, police said.
DIG Bishnu Prasad Rabha said two persons were killed in the firing. They have been identified as Kishori Teli and Rajesh Shah.
The injured were shifted to Assam Medical College Hospital in neighbouring Dibrugarh district.
Police and paramilitary forces have been deployed and security measures tightened in the district, officials said.
On Thursday in Philobari, suspected ULFA-I militants had exploded an improvised explosive device in a drain near Badalbheta Tea Estate but none was injured.
