Yemen's Houthi rebels have been attacking ships in the Red Sea, one of the world's major trade arteries

LONDON — Yemen's Houthi rebels have escalated attacks on ships passing through the Red Sea during the Israel-Hamas war, raising concerns about the impact on the flow of oil, grain and consumer goods through a major global trade artery.

Israeli-linked vessels have been targeted, but the threat to trade has grown this week as a Norwegian-flagged oil tanker was struck and missiles were fired at a vessel carrying jet fuel toward the Suez Canal, where about 10% of the world's trade passes through.

A missile fired from Houthi-controlled territory also missed a Hong Kong-flagged container ship traveling from Oman to Saudi Arabia on Thursday.

The Houthis are Iranian-backed rebels who swept down from their northern stronghold in Yemen and seized the capital, Sanaa, in 2014, launching a grinding war against a Saudi-led coalition seeking to restore the government.

The Houthis have sporadically targeted ships in the region, but the attacks have increased since the start of the Israel-Hamas war.

They have used drones and anti-ship missiles to attack vessels and in one case used a helicopter to seize an Israeli-owned ship and its crew.

In recent days, they have threatened to attack any vessel they believe is either going to or coming from Israel.
