Al Shabaab applies its own ruthless brand of justice again.

Islamists in southern Somalia have stoned a man to death for adultery but spared his pregnant girlfriend until she gives birth.

Abas Hussein Abdirahman, 33, was killed in front of a crowd of some 300 people in the port town of Merka.

An official from the al-Shabab group said the woman would be killed after she has had her baby.
