Only five days into his reign, Saudi Arabia's King Salman oversees beheading

Saudi Arabia’s King Salman bin Abdul-Aziz Al Saud has already overseen his first beheading just days after succeeding his brother, ignoring widespread claims that the case against the man was weak.

The controversial killing of Moussa al-Zahrani came shortly before President Barack Obama arrived in Riyadh on Tuesday to pay respects to the late King Abdullah.

Al-Zahrani, a teacher, was executed in the city of Jeddah. He had been convicted of sexually assaulting underage girls in a string of attacks in 2011. Al-Zahrani had maintained his innocence throughout two appeals and released a 20-minute video urging King Abdullah to intervene last year.

His case drew an unprecedented reaction from those living in Saudi Arabia on social media but King Salman, 79, refused to intervene and he was beheaded on Monday.
