The Houthis said it would continue to target Red Sea shipping until Israel lifted its blockade of Gaza, and that its forces would respond to the strikes. The Iranian-backed rebel group, which considers Israel its enemy, controls Sanaa and the north-west of Yemen, but it is not the country's internationally recognised government. The Houthis have said they are acting in support of the Palestinians in the war between Israel and Hamas in Gaza, and have claimed - often falsely - that they are targeting ships only linked to Israel, the US or the UK.
