Hundreds of protesters have demonstrated outside Thailand's embassy in Yangon after two Myanmar migrants were sentenced to death by a Thai court for murdering two British backpackers.
The verdict has sparked much anger in Myanmar, previously known as Burma.
Zaw Lin and Win Zaw Tun were found guilty yesterday of killing David Miller, 24, and of the rape and murder of Hannah Witheridge, 23.
The bodies of the victims were found on a beach on the southern Thai diving resort of Koh Tao in September last year.
The convictions have raised questions over Thailand's justice system; the defence accused the police of bungling their investigation and using the men as scapegoats - a charge authorities deny.
Hundreds of people, including monks, gathered in Yangon to protest the verdict, many saying they believed the two men had been wrongly convicted.
A police cordon stopped protesters demonstrating opposite the embassy itself, confining them to the end of the street instead.
Prosecutors say evidence was 'rock solid'
Thailand has warned its citizens to take care in Myanmar following the verdict.
Thai prosecutors and police insist their evidence against the men was rock solid, including DNA found on Ms Witheridge's body.
But the defence, which has vowed to appeal the verdict, disputed the forensic evidence, saying it was improperly collected and processed.
They also accused the police of torturing their clients into signing confessions, which they later retracted.
Amnesty International has called on Thai authorities to fully investigate the torture allegations, something the rights group said had yet to happen.
Activists say the case reflects a wider trend of low-paid migrant workers from neighbouring countries being blamed for crimes in Thailand where the justice system is easily bent by wealth and power.
