Ship-tracking data shows the number of vessels transiting the Strait of Hormuz increased on Tuesday, and most of them had traded with the Islamic Republic.

Reuters wrote that the move took place just before a U.S. maritime blockade began.

Kpler Institute data shows that of 11 ships that passed through the Strait on Tuesday, 9 crossed via the Islamic Republic route.

CNN also, citing the Windward Institute, wrote that 23 Islamic Republic ships in the Strait of Hormuz operate with false flags, disable their receivers, or use other concealment methods, and seven supertankers carrying crude oil have remained idle on the water in the Indian Ocean.

Traffic in the Strait of Hormuz on Wednesday remained slow hours after the start of a U.S. maritime blockade on Islamic Republic shipping, and only a small number of ships dared to pass.

According to Bloomberg, based on tracking data, a Greek Suezmax tanker carrying Saudi oil reappeared near Fujairah after three days of signal cutoffs.
