Myanmar's junta has suspended the issuing of permits for men to work abroad, it has said, weeks after introducing a military conscription law that led to thousands trying to leave the country.

The junta, which is struggling to crush widespread armed opposition to its rule, said in February it would enforce a law allowing it to call up all men to serve in the military for at least two years.

The move sent thousands queuing for visas outside foreign embassies in Yangon and others crossing into neighboring Thailand to escape the law, according to media reports.
