The United States and Britain launched strikes from the air and sea against Houthi military targets in Yemen in response to the movement’s attacks on ships in the Red Sea, a dramatic regional widening of the Israel-Hamas war in Gaza.
As witnesses in Yemen confirmed explosions throughout the country to Reuters, Joe Biden, the US president, cautioned in a statement late on Thursday he would not hesitate to take further action if needed.
But the Iran-aligned group has been active for some time.
History
In the late 1990s, the Houthi family in far north Yemen set up a religious revival movement for the Zaydi sect of Shi’ite Islam, which had once ruled Yemen but whose northern heartland had become impoverished and marginalised.
As friction with the government grew, they fought a series of guerrilla wars with the national army and a brief border conflict with Sunni Saudi Arabia.
War in Yemen
The war began in late 2014 when Sana’a was seized by the Houthis. Worried by the growing influence of Shi’ite Iran along its border, Saudi Arabia intervened at the head of a Western-backed coalition in March 2015 in support of the Saudi-backed government.
