Turkish President Recep Tayyip Erdogan Sunday urged Muslim countries to “use every means available” to stop the “cruelty” perpetrated against Myanmar’s Rohingya.

“We want to work with the governments of Myanmar and Bangladesh to prevent the humanitarian plight in the region,” he told the opening session of an Organisation of Islamic Cooperation (OIC) summit in the Kazakh capital Astana.

Erdogan said Turkey had offered aid and said he expected that Bangladesh authorities admit and help Rohingya Muslims fleeing the violence in Myanmar.

“International organisations, and we as Muslim countries in particular, should fight together by using every means available to stop that cruelty,” he said. Erdogan had previously promised to raise the Rohingya issue at the annual meeting of UN General Assembly later this month.

A final statement was agreed on at Sunday’s OIC summit – the first such summit on Science and Technology. Kazakhstan President Nursultan Nazarbayev said it was thanks to the efforts of the Turkish delegation that such a statement was prepared.

Erdogan called on “the brothers around the table” to follow and implement the decisions.

“The meeting called upon the government of Myanmar to accept the UN Human Rights Council’s fact-finding mission to conduct a thorough and independent investigation into all alleged violations of international human rights law and to bring the perpetrators to justice,” said the statement.

Rohingya, described by the UN as the world’s most persecuted people, have faced heightened fears of attack since dozens were killed in communal violence in 2012.

Last October, following attacks on border posts in Rakhine’s Maungdaw district, Myanmar security forces launched a five-month crackdown in which, according to Rohingya groups, around 400 people were killed.
