MOSCOW, January 12. /TASS/. The armed forces of the United States and the United Kingdom delivered strikes on positions held by the Ansar Allah (Houthi) rebel movement in Yemen in the early hours of Friday.

Below is a brief summary of those events.

How it all began

- After the escalation of the Palestinian-Israeli conflict in the Gaza Strip, the Houthis claimed that they would launch strikes on Israeli territory and would not allow ships associated with it to pass through the waters of the Red Sea and the Bab el-Mandeb Strait until the operation in the Palestinian enclave stopped.

- Late on January 11, The Times reporter Steven Swinford wrote on the X social network (formerly known as Twitter) that UK Prime Minister Rishi Sunak has briefed members of the UK Cabinet "on imminent military intervention this evening."

- The Houthi movement vowed retaliation to any potential attack by the United States and the United Kingdom.

Strikes on Houthi positions

- In the early hours of Friday, the Al Hadath television reported that forces of the United States and the United Kingdom had delivered strikes on positions held by the Ansar Allah movement near the western Yemeni port city of Hudaida

- Explosions were heard in the Yemeni cities of Sana’a, Sa’dah, Hudaydah, Taizz and Dhamar, Al Hadath said.

- Friday’s strike targeted more than 10 facilities in Yemen used by Ansar Allah, CNN said citing own sources.

Remarks by Biden and Sunak
