New Delhi: Congress president Sonia Gandhi on Monday expressed concern over the deaths and destruction caused by an earthquake in the north-eastern states of the country.

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.

The quake, measuring 6.7 on the Richter Scale, occurred at 4:37 a.m and had its epicentre in Manipur’s Tamenglong district bordering.

 The earthquake was felt in parts of Manipur, Assam, Arunachal Pradesh, Meghalaya, Nagaland, Mizoram and Tripura.

At least 8 people were killed and another 100 injured when an earthquake measuring 6.7 on the Richter scale rocked West Bengal and north-eastern states early on Monday. The injured have been admitted at state government hospital JNIMS in Imphal.

Several buildings have collapsed in the state capital, and many others have suffered structural damage.

India’s north-east region is considered the sixth major earthquake-prone belt in the world. In September 2011, Sikkim suffered heavy damage following a quake.
