Some 57 ships carrying an estimated 1,100 seafarers have transited the Strait of Hormuz since 23 June under a United Nations evacuation plan launched this week, data from the UN's shipping agency showed on Thursday.

These are the first numbers to be released by the UN's International Maritime Organization (IMO) for the initiative, which will enable hundreds of ships with some 11,000 seafarers to leave the strait.

According to current IMO data, 12 ships sailed through during the morning of 25 June, 32 on 24 June and 13 on 23 June.
