Houthi rebels in Yemen have launched a violent new wave of attacks on ships in the Red Sea, sinking two vessels and killing crew members.

Houthi rebels in Yemen attempted to strike Israel’s Ben Gurion airport after sinking two vessels in the Red Sea this week, as the group ramps up its military pressure in support of Palestinians under Israeli fire in its bid to bring the war in Gaza to an end.

Israel has carried out its first strikes against Houthi targets in Yemen since the Israel-Iran ceasefire, attacking ports and a power plant around midnight local time Sunday night into Monday morning.
