Saudi Arabia executes 37 citizens over alleged terrorism offences

Saudi Arabia has executed 37 citizens across the country for alleged terrorism-related crimes, publicly pinning one of their headless bodies to a pole as a warning.

The mass execution on Tuesday was the biggest in a single day in Saudi Arabia since January 2016, when 47 people were killed, including a prominent Shia cleric whose death prompted protests in Iran and the ransacking of the Saudi embassy in Tehran.

The executions took place days after four Islamic State gunmen died while trying to attack a Saudi security building north of the capital, Riyadh, and following Easter Sunday bombings claimed by Isis that killed more than 300 people in Sri Lanka.
