British and American ships are tentatively returning to the Red Sea after Yemen’s Houthi rebels vowed to hold off attacks on vessels linked to both nations, a sign that traffic on one of the world’s main trade routes could normalize after more than a year of disruption.

Shipping companies expressed caution about using the shorter route between Asia and Europe that many ships have avoided for more than a year.

Yemen’s Houthi rebels have signaled they will limit their attacks in the Red Sea corridor to only Israeli-affiliated ships as a ceasefire in the Gaza Strip takes hold.

The world’s top three container operators said they fear instability in Gaza and broader regional tensions mean continued danger.

Yemen’s Iran-backed Houthi movement has released the crew of a cargo ship more than a year after its fighters hijacked the vessel in the Red Sea, as part of its campaign of attacks in support of Hamas in its war against Israel.

The Yemen-based Houthis signaled a pause in their months-long attacks on commercial ships following a ceasefire deal between Israel and Hamas.

Following the ceasefire agreement between Israel and Hamas, Yemen's Houthi rebels have also declared a truce in the Red Sea. The Houthis, who receive support from Iran, have announced an end to their attacks in this strategically significant trade route.

Mandeb strait decreased by 50% after the Yemeni rebels launched maritime attacks, according to the US Energy Information Administration.
