We took a look at the significant underreporting of US counter terrorism strikes in Yemen. YDP's list of 21 US drone strikes since Jan.2025 is 4x higher than the number recorded by other international orgs. More on the recent strikes in America's forever war in Yemen 👉 mailchi.mp/cd4323bd1138...

A picture uploaded to social media of a vehicle purportedly hit by a US drone strike in the city of Al Ghaydah, Al-Mahrah governorate on 12 February 2026. Additional images indicate the munition was likely the bladed (rather than explosive) R9X Hellfire missile. An alleged AQAP member, a Somali national, was reportedly killed in the strike.

The British base at Diego Garcia has been back in the spotlight after Kier Starmer initially refused to give permission for US bombers to deploy from the island airbase for strikes against Iran, despite previously allowing American B-2 Spirits to launch bombing runs into Yemen from there last year.
