A Tunisian soldier opened fire at a military base in the capital on Monday, killing seven colleagues and wounding 10 others before being shot dead himself, according to the army which said the shooter had "family problems". What exactly triggered the shooting at the Bouchoucha base in Tunis was not immediately clear, but the incident alarmed residents in the capital city still on edge after an attack in March by Islamist gunmen on the Bardo national museum. When gunfire erupted on Monday morning, police evacuated a nearby school, as locals feared they may be under attack.
