Hollywood star Angelina Jolie has condemned the violence against Rohingya Muslims in Myanmar and called on the country's government and its leader, Nobel Peace Prize recipient Aung San Suu Kyi, to no longer remain silent.
"We are potentially going to have one of the world's largest IDP (internally displaced persons) camps in one concentrated area", a spokesman for the organisation said.
Amnesty International WA president Leonie Alexander said the Government could do more. CAFOD partner, Caritas Bangladesh, is responding to the refugee crisis by providing emergency aid.
He said the not-for-profit's capacity and resources as humanitarian aid agencies were insufficient to cover the needs of all people that now needed assistance.
As Dhaka struggled to cope with the scale of the "unprecedented crisis", dozens of refugees were found in three towns hundreds of kilometres from the Myanmar frontier, stoking fears that thousands of Rohingya Muslims will move from the border region into the the mainland of Bangladesh.
"At the moment there's well over 50,000 people that we observed, literally yesterday, on the roadsides, settling in makeshift camps in very precarious conditions".
"That number could rise beyond one million by the end of the year if the influx continues, including about 600,000 children, according to United Nations agencies", Mark Pierce, the Bangladesh chief of Save the Children charity, said.
The authorities plan to construct 14,000 shelters, each with the capacity to hold six families, with the help of worldwide aid organisations and the Bangladesh military.
