Wa Lone and Kyaw Soe Oo were earlier this week honoured among other persecuted or killed journalists as Time magazine's persons of the year.

They were sentenced to seven years in jail for violating a state secrets act while reporting on the Rohingya crisis.The case has been widely seen as a test of press freedom in Myanmar.Supporters of the pair planned to gather in central Yangon on Wednesday evening, while people from around the world posted photos on social media of the "thumbs up" gesture that became a symbol of the pair's court appearances.The two journalists had been investigating the murders of 10 Rohingya men by the army in the northern Rakhine village of Inn Dinn.They were detained in December last year while carrying official documents they had been given by two police officers.

They have always maintained their innocence and say they were set up by the police.TheIndianSubcontinent Myanmar correspondent Nick Beake said the pair's award-winning investigation forced a rare admission of guilt from the still powerful Burmese military.

But it made no difference at their trial, he adds, explaining that for many, it was a farce - as seen when a police whistle-blower admitted that the reporters had been set up, before he too was jailed.

She defended the verdict saying the two journalists had broken the law and that their conviction had "nothing to do with freedom of expression at all".She's also facing criticism for not speaking up for the Muslim Rohingya minority.

Since last year, at least 700,000 Rohingya have fled Myanmar, also known as Burma, after the army launched a brutal crackdown in response to attacks by a Rohingya militant group.The UN has called for top military figures to be investigated for genocide.
