Yemen

On Saturday in the Yemeni capital of Sanaa, two bombs were dropped by Saudi warplanes. They were targeting a convention centre where a wake was being held for the father of a well-known local leader from the Shia Houthi, who have controlled the Yemeni capital since 2014.

One hundred and forty people died, 500 were wounded. The military terminology for such an attack is known as a “double tap”, in which the first bomb causes the casualties and the second bomb is aimed at the first responders. It is the military equivalent of the old terrorist tactics of detonating two bombs at the same site; one to kill the initial target and the other to target those trying to help the initial victims.
