Al Jazeera reports the U.N. says it will begin investigating attacks on its facilities during Israel's recent war against Hamas in Gaza, that killed more than 2,100 Palestinians. U.N. Secretary-General Ban Ki-moon said on Tuesday that the world body was investigating a deadly strike near one of its schools in the Gaza Strip and the alleged use of U.N. sites to store weapons. "I am planning to move forward with an independent board of inquiry to look into the most serious cases, as well as instances in which weaponry was found on U.N. premises," Ban said at a monthly meeting of the UN Security Council. More than 2,100 Palestinians, most of them civilians, were killed during 50 days of fighting in July-August between Israel and Palestinian groups; while 108,000 people remain homeless. Ban's spokesman Stephane Dujarric said the inquiry was standard procedure whenever UN facilities are targeted.
