The secretary general of the world's largest bloc of Islamic countries says meetings with members of Myanmar's long-persecuted Rohingya Muslim community — chased from their homes by machete-wielding Buddhist mobs — brought him to tears.

Ekmeleddin Ihsanoglu made the comments as he and other members of the Organization of Islamic Cooperation wrapped up a four-day visit to the country Sunday that included talks with the president, ministers, interfaith groups and U.N. agencies.

But it was the huge, emotional crowds living in trash-strewn camps outside of Sittwe — where streets are now all but devoid of Muslims — that made the biggest impression.

"I've never had such a feeling," he said. "I was crying."
