AIZAWL, AUGUST 22 (PTI): Local volunteers helped 22 families to evacuate their houses and shift to safer places due to sinking of land at Hunthar locality of Mizoram's capital city here, state Disaster Management and Rehabilitation Director C Lalpeksanga today said. Lalpeksanga, who visited the place this morning told PTI seven houses have been dismantled by the volunteers since yesterday as another spell of rain was most likely to sweep away the houses. He said many displaced families were living with relatives while temporary accommodation arrangements were made for others in government buildings constructed for urban poor and the proposed office of Legal Metrology.
