Security officials in Algeria say four police officers were killed in an attack by suspected Islamic militants in the west of the country.

Officials said the police officers were ambushed on Wednesday while patrolling the coastal town of Gouraya, west of the capital Algiers.

Meanwhile, officials say the number of people killed in a separate attack in Tiaret on Tuesday night has risen to 10.

Five of the victims were children.

Algerian officials said they believed the Armed Islamic Group or GIA was behind both attacks.
