Riyadh: Saudi Arabia on Thursday executed one of its citizens for murder, bringing to 55 the number of convicts put to death this year.

Authorities in the southwestern region of Aseer carried out the death sentence against Owaidhah Al Saadi, the interior ministry said in a statement.

A court found him guilty of shooting dead another Saudi following a dispute, it said.

Most executions in Saudi Arabia are done by beheading with a sword.

The kingdom on January 2 executed 47 people in a single day for terrorism.

According to an AFP tally, Saadi is among eight other locals and foreigners put to death this year.

Last year the kingdom executed 153 people, mostly for drug trafficking or murder, according to an AFP tally.

The number of executions in Saudi Arabia in 2015 was the highest for two decades.

The kingdom practises a strict legal code under which murder, drug trafficking, armed robbery, rape and apostasy are all punishable by death.
