YANGON (Reuters) - A Myanmar judge on Monday found two Reuters journalists guilty of breaching a law on state secrets and jailed them for seven years, in a landmark case seen as a test of progress toward democracy in the Southeast Asian country. Yangon northern district judge Ye Lwin said Wa Lone, 32, and Kyaw Soe Oo, 28, breached the colonial-era Official Secrets Act when they collected and obtained confidential documents. "The defendants ... have breached Official Secrets Act section 3.1.c, and are sentenced to seven years," the judge said, adding that the time served since they were detained on Dec. 12 would be taken into account. The defense can appeal the decision to a regional court and then the supreme court. The verdict comes amid mounting pressure on the government of Nobel laureate Aung San Suu Kyi over a security crackdown sparked by attacks by Rohingya Muslim insurgents on security forces in Rakhine State in west Myanmar in August 2017. More than 700,000 stateless Rohingya Muslims have fled into Bangladesh since then, according to U.N. agencies. The two reporters, who were investigating the killing by the security forces of Rohingya villagers at the time of their arrest, had pleaded not guilty.
