Non-violent tactics have sometimes been met with Israeli military force. For example, Amnesty International notes that "10-year-old Naji Abu Qamer, 11-year-old Mubarak Salim al-Hashash and 13-year-old Mahmoud Tariq Mansour were among eight unarmed demonstrators killed in the early afternoon of May 19, 2004 in Rafah, in the Gaza Strip, when the Israeli army open fire on a non-violent demonstration with tank shells and a missile launched from a helicopter gunship. Dozens of other unarmed demonstrators were wounded in the attack." According to Israeli army and government officials, the tanks shelled a nearby empty building and a helicopter fired a missile in a nearby open space in order to deter the demonstrators from proceeding towards Israeli army positions.
