SINGAPORE, Sept 9 (Reuters) - Six commodity vessels transited the Strait of Hormuz on Tuesday, ‌down from nine a day earlier and ‌below the 10-day average of about 12, preliminary shipping data ​showed on Wednesday.

The figures could change as some ships typically switch off their transponders during the voyage.

Of the six vessels, five were entering and ‌one was exiting, ⁠initial data from shiptracker Kpler showed at 0200 GMT. They included one ⁠Panamax and one intermediate tanker.

The U.S.-Israeli war on Iran intensified on Tuesday with Tehran-backed Houthis in ​Yemen launching ​strikes on several Saudi ​Arabian cities, further ‌embroiling a U.S. ally in the conflict. In addition, American forces hit multiple Iranian oil tankers and Iran struck a U.S. base in Jordan.

Meanwhile, 25 commodity vessels transited the Bab el-Mandeb strait ‌on Tuesday, another major maritime ​chokepoint in the Middle ​East, with 11 ​vessels entering and 14 exiting.

This compares ‌with an average of around ​27 ships ​going through Bab el-Mandeb over the past 10 days.

Among the vessels travelling through the strait ​were two ‌Suezmax tankers, eight Aframax tankers and one ​Very Large Crude Carrier.
