Algiers  - Seven Algerian soldiers were killed in two separate incidents by suspected Islamist terrorists, local media reported on Tuesday.

At Tebessa, some 630 kilometres east of the capital Algiers, four soldiers died when a bomb exploded under a lorry carrying military supplies late Sunday.

A second bomb targeting another lorry seriously injured six other soldiers.

Also on Sunday, three soldiers were killed after the bus on which they were traveling was stopped at a roadblock erected by suspected Islamist rebels near the city of Boumerdes, some 50 kilometres east of Algiers.

Witnesses said the attackers killed the soldiers with knives and then filmed the gruesome scene.

The group Al Qaeda in the Islamic Maghreb - formerly known as the Salafist Group for Preaching and Combat (GSPC) - has carried out a number of bloody attacks in Algeria since associating itself with terrorist chief Osama bin Laden in early 2007. (dpa)
