Congress president Sonia Gandhi on Monday expressed concern over the deaths and destruction caused by an earthquake in north-eastern states.
The party has asked its chief ministers in the region to ensure immediate relief and rescue operations besides asking its units and frontal organisations to help out in relief work.
At least six people were killed and over 60 injured when an earthquake measuring 6.7 on the Richter scale rocked West Bengal and north-eastern states early on Monday.
