In 2006, one person attacked three churches in Alexandria, killing one person and injuring 5–16. The attacker was not linked to any organisation and described as "psychologically disturbed" by the Ministry of Interior. In May 2010, The Wall Street Journal reported increasing waves of mob attacks by Muslims against ethnic Copts. Despite frantic calls for help, the police typically arrived after the violence was over. The police also coerced the Copts to accept "reconciliation" with their attackers to avoid prosecuting them, with no Muslims convicted for any of the attacks. In Marsa Matrouh, a Bedouin mob of 3,000 Muslims tried to attack the city's Coptic population, with 400 Copts having to barricade themselves in their church while the mob destroyed 18 homes, 23 shops and 16 cars.
