Saudi authorities on Sunday beheaded a citizen convicted of shooting a man in the head with an assault rifle, the Interior Ministry said.

In a statement carried by the official Saudi Press Agency, the ministry said that Ali bin Suweid Al-Domnan killed Diyab bin Ali al-Mansour following an argument in the southern city of Najran.

Saudi Arabia follows a strict interpretation of Islam under which those convicted of murder, drug trafficking, rape and armed robbery are executed in public with a sword.

Sunday's execution brought to 136 the number of people beheaded in the kingdom this year, according to an Associated Press count. Saudi Arabia beheaded 38 people last year and 83 people in 2005.
