The Red Sea has been the focus of world news in recent weeks, in particular after military strikes by the United States and United Kingdom against Houthi positions in Yemen on 12 January.
These bombing raids were aimed at compelling the Houthis to stop attacking ships heading into or out of the Red Sea in a busy trade route that passes alongside the western coast of Yemen, which the Houthis control.
Later, the US launched solo strikes, this time targeting a drone-guiding radar facility, as both London and Washington aim to make their point, both to the Houthis and to Iran.
The joint Anglo-American operation followed a UN Security Council resolution denouncing the Houthi offensives, demanding their immediate cessation, and authorising nations to defend their commercial interests from threats.
Punch and counterpunch
The US and UK say their strikes were in retaliation after 27 Houthi assaults on vessels since 19 November.
Their attacks, involving drones and missiles, have impacted more than 50 nations and targeted both cargo and military ships in the Red Sea.

Most notably, the Houthis filmed themselves hijacking the Galaxy Leader, a car carrier built in Poland, which sails under the flag of the Bahamas and is owned by a Japanese company and an Israeli businessman.
The Houthis detained its crew and relocated them to a Houthi stronghold off the Hodeidah coast, declaring that its actions on the high seas would continue until Israel ended its war in Gaza.
