Since 12 January 2024, the United States and the United Kingdom, with support from Australia, Bahrain, Canada, Denmark, the Netherlands, and New Zealand, have launched a series of cruise missile and airstrikes, codenamed Operation Poseidon Archer, against the Houthi movement in Yemen in response to Houthi attacks on ships in the Red Sea. The Houthis had previously declared that their attacks are in support of Palestinians during the 2023 Israel–Hamas war; Houthi attacks on shipping were condemned by the United Nations Security Council the day before the initial strike.

Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state at standard conditions for temperature and pressure.
