Saudi Arabia has executed two soldiers who were convicted of treason as the kingdom conducted its war on Yemen’s Houthi rebels.

A brief statement on the state-run Saudi Press Agency identified the two as a lieutenant colonel who was a pilot and a chief sergeant.

It did not elaborate on what they allegedly did, other than to accuse them of having “committed a number of major military crimes” during a period of the war.

Report says Saudi Arabia typically beheads those it executes, and is among the world’s top executioners.
