A British joining of Saudi escalation efforts against Yemen

Aviation tracking sites showed two refueling aircraft belonging to the UK flying over the Red Sea towards Saudi Arabia, coinciding with the Saudi escalation with airstrikes in Yemen.
Follow-ups – Al-Khabar Al-Yemeni:
Although the British effort in the war against Yemen is not new, as it has been a key actor in the war since 2015 according to British reports, the direct participation of the British Air Force alongside Saudi Arabia moves London from the realm of logistical support and planning to the execution arena.
