Seven pilgrims from Punjab's Mohali drowned in the Gobind Sagar lake in Himachal Pradesh's Una district on Monday, officials said.

Himachal Pradesh State Disaster Management Department said they were part of a group of 11 pilgrims, and the incident happened when they entered the lake near Garib Nath temple in Bangana sub-division to take bath.

Out of the 11, four managed to come out after some time while the rest seven did not, the department added.

Officials said seven bodies have been fished out of the water.

A press note issued by the state's public relations department said Chief Minister Jai Ram Thakur expressed grief over the incident.

Punjab chief minister Bhagwant Mann and Shiromani Akali Dal chief Sukhbir Singh Badal condoled the death of pilgrims.

"Sad news of drowning of seven youths from Banur (in Mohali) in Punjab, who stopped for taking bath in the Gobind Sagar Lake while being on the way to Baba Balak Nath," Mann tweeted.

Badal said, "It is very sad & tragic. My heart goes out to the bereaved families. May Gurusahab grant them enough strength to bear this terrible loss."
