Head of the Matariya Investigation Office, Col. Wael Tahoun and his car driver were shot dead late Tuesday in front of the colonel's house, according to Al Bawaba News. The assault was carried out by two unidentified gunmen who opened fire on Tahoun's car then detonated an improvised explosive device near his house to distract attention from their crime, before fleeing the scene on a motorbike. "Two unidentified gunmen opened fire on Tahoun's car in Cairo's Ain Shams district, while he leaving for work. The incident led to his and his driver's death," Interior Ministry spokesperson Hany Abdelatif said. Bomb disposal officers were deployed to the blast scene to scan the area for other potential threats. On Monday, four people, including policemen, were injured in a bombing targeting Matariya Police Station. The attack came last in a series of assaults targeting security and military personnel across Egypt since mid-2013, when Islamist president Mohamed Morsi was ousted amid popular protests.
