Myanmar hit by 6.8 magnitude earthquake; tremors in Kolkata, Bangkok

A 6.8 magnitude earthquake has hit central Myanmar, and was felt in Thailand, Bangladesh and India, reports say.

The quake struck 25km (15.5 miles) west of Chauk, at a depth of 84km, the US Geological Survey said.

According to BBC, no casualties have yet been reported but the quake hit near the ancient city of Bagan, a major tourist site.

Buildings shook in Yangon, Myanmar's largest city and the Thai capital Bangkok.

Underground railway services have been suspended in the Indian city of Kolkata, the AFP news agency reports.

At least 20 people were injured in the Bangladeshi capital, Dhaka, as they fled a building, local media report.

Early reports have suggested temples at Bagan, the site of thousands of Buddhist monuments, may have been damaged.
