Over 1,000 tourists have got stranded at the St Martin's coral island in the Bay of Bengal due to inclement weather.
Local administration asked the tourists not to leave the island until the weather improves, said Hasib Uddin Badal, vice-president of Cox's Bazar Tour Operators' Association.
The authorities suspended vessel movement on Teknaf-St Martin's route due to rough sea under the influence of depression over the Bay.
However, all the tourists are now safe, said Hasib Uddin.
On March 5, around 3,000 tourists went to the island. Among them, 11,00 did not return for passing night over there.
Rabiul Hasan, upazila nirbahi officer of Teknaf upazila, said the tourists would be brought back to Teknaf once the weather gets normal.
