At least 10 people have been killed in a strike near a UN-run school housing Palestinians displaced by the Gaza conflict, medics say.

The attack hit the entrance of the facility in Rafah, where thousands of Palestinians are said to be sheltering.

UN Secretary General Ban Ki-moon described the attack as a "moral outrage and a criminal act".

JERUSALEM (CNS) — With close to a quarter of a million Palestinians rendered homeless by the continuing and intensifying fighting between Hamas and Israel in Gaza, the Coordinating Catholic Aid Organizations met three times in as many days to organize action to confront the humanitarian crisis.

In addition to the current material needs — food, water, personal hygiene items, medicine and diesel fuel for generators — the Catholic aid associations from the Holy Land, U.S. and Europe are beginning to plan for the psychosocial needs of Gazans at the eventual end to the confrontation.
