The Iranian-backed Houthis have increased threats to return to attacks on Israel and ships, claiming that Israel has cut off aid to Gaza. Iran wants to use the Houthis to pressure Israel and keep the conflict in Gaza ongoing. The Houthis have given an ultimatum to international mediators, stating that they will restart naval operations against Israel if aid delivery to Gaza is not resumed. It is unclear if the Houthis will follow through on their threats.
