The United States is calling on Burma to lift travel restrictions on humanitarian workers trying to get to Arakan State, where tens of thousands of Muslims are living in displacement camps. Hundreds of aid workers fled the state last week after extremist Buddhist mobs attacked their residences and offices, accusing them of favoring Muslims. Several aid agencies sought to return but were denied permission. The US called on the government to facilitate the appropriate travel authorizations to UN and other humanitarian organizations so they could get back to work. Aid groups say clean water and food stocks are starting to run out. Emergency medical referrals are at a near standstill.—AP
