Rohingya Muslim insurgents in Myanmar have declared a one-month unilateral ceasefire to ease the humanitarian crisis in northern Rakhine state. Arakan Rohingya Salvation Army (Arsa) said the truce will start today. Arsa also urged Mynamar's army to lay down weapons as well. Arsa attacks on police last month triggered a response by the military. About 2.9 lakh Rohingya are said to have fled Rakhine and sought shelter over the border in Bangladesh since then. The UN says, there is a desperate need for food, water and health services for new arrivals in Cox's Bazaar. It said, the aid groups urgently need 77 million dollars to help Rohingya who have fled Myanmar.
