Thais living or travelling in Myanmar are being advised to avoid areas under martial law, particularly in northern Shan State, for their own safety.
The travel warning was issued by the Thai embassy in Yangon. Thais should avoid travelling to those areas, the embassy said.
The embassy said Myanmar had banned foreigners from buying air tickets to Lashio and Tachilek in Shan State since May this year. Violators could be jailed or fined under immigration law.
