At least 74 people were killed in a strong earthquake that struck Myanmar, state media said on Friday, while a series of aftershocks have caused panic but only limited damage in Thailand and Laos. The death toll from Thursday's 6.8 magnitude tremor was expected to rise slightly in Myanmar after 225 homes and nine government buildings were destroyed. Over 100 people were injured, according to state television. The quake sparked panic, but no major damage, in other countries across Southeast Asia. [Xinhua]
