YANGON, Burma (AP) — Burma is vowing to protect U.N. and humanitarian aid workers seeking to return to the strife-torn state of Rakhine after rampaging Buddhist mobs attacked the workers’ homes and offices.

State-run media also said Wednesday the government would expose those who orchestrated and joined last month’s attacks.

Burma has come under mounting international pressure to restore life-saving aid in the state, which is home to around 1.3 million Rohingya Muslims, who the U.N. considers one of the most persecuted religious minorities in the world.

More than 140,000 are living in crowded camps — dependent on food, water and medical care provided by international relief organizations — after their neighborhoods were destroyed by Buddhist extremists.

Some aid workers have tried to return in recent days but have been denied necessary permits.
