YANGON - Aftershocks rattled central Myanmar after an earthquake that killed at least 11 people, with that toll likely to rise on Monday as several workers were missing after a half-built bridge collapsed on the Irrawaddy River.

The magnitude 6.8 earthquake early on Sunday struck about 60 km (37 miles) northwest of Mandalay, Myanmar's second-biggest city, near the town of Shwebo. It was felt in Thailand and other neighboring countries.

Several large aftershocks were felt during the day and state television said one of 5.7 magnitude hit just after midnight.

"We can confirm that a total of 11 are dead, while over 50 are injured and four are missing," a senior official at the Ministry of Relief and Resettlement told Reuters, asking not to be identified as he was not authorized to speak to the media.
