A strong earthquake with a preliminary magnitude of 6.8 hit northeastern India on Sunday near the border with Nepal. Reports said several people were injured and some buildings fell in the capital of India's Sikkim state. The quake, centered in Sikkim, was felt over a broad area. It triggered at least two aftershocks of magnitude 6.1 and 5.3, Indian seismology official R.S. Dattatreyan said. He warned that more aftershocks were possible. Regional TV station NewsLive reported that some buildings collapsed in Sikkim's state capital of Gangtok. It said several people were rushed to hospitals but gave no further details. Calls to city officials, police and hospitals did not go through. In neighboring Nepal and Bangladesh, the quake sent residents rushing out their homes, offices and shopping centers. Members of parliament who were debating the national budget in Katmandu, Nepal's capital, ran out of the assembly hall into a parking area. They returned 15 minutes later and resumed their session. Elsewhere in the city, police said four people were hurt when a wall collapsed but their injuries were not serious. Initial reports said the earthquake damaged some houses in northeastern Nepal near the epicenter but details were sketchy.
