Rohingya Muslims have for decades suffered from state-sanctioned discrimination in Myanmar.
Attacks on the religious minority by Buddhist mobs in the last three years have sparked one of the biggest exoduses of boat people since the Vietnam War, sending 100,000 people fleeing, according to Chris Lewa, director of the Arakan Project, which has monitored the movements of Rohingya for more than a decade.
Last week, the UN's refugee agency said in a statement that an estimated 25,000 Rohingyas and Bangladeshis boarded people smugglers' boats in the first three months of 2015, twice as many in the same months of 2014.
"Based on survivor accounts, we estimate that 300 people died at sea in the first quarter of 2015 as a result of starvation, dehydration and abuse by boat crews," the statement said.
In the past weeks dozens of corpses , believed to be of Rohingya, were found in Thailand.
Not only Australia and the EU countries put migrants into detention. Malaysian police say more than 1,000 migrants from Myanmar and Bangladesh have been found "illegally" trying to enter the country at the popular resort island of Langkawi. "All the illegal immigrants that have been arrested will be sent to detention centres," said Mohd Yusof Abdullah, commander of the Langkawi marine police. The migrants were found in "very poor condition," suffering from severe thirst and hunger. The migrants were found a day after boats carrying about 500 members of Myanmar's long-persecuted Rohingya community washed ashore in western Indonesia.
