Myanmar's de facto leader Aung San Suu Kyi has scrapped plans to attend a United Nations General Assembly meeting later this month, her spokesman said Wednesday, as the Nobel laureate faces intense global scrutiny over the Rohingya refugee crisis.

"The state counsellor won't attend the meeting of the United Nations General Assembly," said government spokesman Zaw Htay, using Suu Kyi's formal title, without giving further details.
