Thirty-seven commodity ships passed through the Bab el-Mandeb strait on Tuesday, the highest number since July 19, preliminary shipping data showed, with only a few transiting through the Strait of Hormuz, Reuters reports.

Of the ships passing through, 20 ships entered the strait while 17 ships exited, according to ship-tracking data from analytics firm Kpler. None were very large crude carriers or liquefied natural gas tankers.
