More hostages were killed during the siege of an Algerian gas plant than had previously been thought, the Algerian government has said.

Five suspected members of the Islamist group which held foreign and local workers hostage at the In Amenas gas installation have been arrested, reports say.

The reports came a day after the Algerian authorities said all 32 hostage-takers had been killed at the plant.

It is known three Britons are among the dead, with another three UK citizens and a British resident believed to be dead, according to British Prime Minister David Cameron.
