According to Morocco World News, Alarabiya and other media, Algerian authorities are searching for three terrorists who attempted to target Annaba Theatre, a theatre in the north-eastern city of Annaba, where raï singer Cheb Khaled was performing on 9 December 2015.
A separate report by Russia Today cited Algerian media sources as saying that the Algerian army successfully thwarted the attack, but were unable to arrest the terrorists.
Multiple Algerian media reports suggested that the terrorists infiltrated to Annaba from the Eastern borders of Algeria. Algerian authorities have not yet issued any statement regarding the incident.
The north-eastern city where the whereabouts of the terrorists are suspected is hosting the Annaba Festival of Mediterranean Cinema, which began on 4 December 2015.
