TEHRAN: Iran's Red Crescent said Thursday it has prepared an aid package for Myanmar's Rohingya Muslims as they flee a crackdown by security forces, local media reported.

"An emergency, food, life support, and hygiene packages have been prepared by the Red Crescent to be sent to Myanmar," said the head of the organisation Morteza Salimi, according to the ISNA news agency.

The aid package would be "immediately sent to the oppressed people of this country if we receive authorisation from Myanmar," he said, adding it had been ordered by President Hassan Rouhani.

Iranian officials have repeatedly condemned the massive security operations by the Myanmar army that followed a series of deadly ambushes by Rohingya militants on Aug 25.

The United Nations says 164,000 refugees have so far fled to neighbouring Bangladesh.

Iran's ambassador to the UN, Gholam Ali Khoshrou, on Thursday said he was working to bring together ministers and diplomats from several Islamic countries to discuss the issue.

"I have had numerous contacts with ambassadors of Islamic countries in recent days and it was decided to form a group at the ambassadorial and ministerial levels," he said, according to state news agency Irna.

He said he hoped the group could meet in New York when the UN General Assembly convenes next week.

"Everyone must make an effort to stop this human catastrophe," he said.
