UNITED NATIONS, July 24 (Reuters) - U.N. Secretary-General Ban Ki-moon said on Thursday he was appalled by an attack on a U.N.-run school in the northern Gaza strip that had killed women, children and U.N. staff.
"Circumstances are still unclear. I strongly condemn this act," Ban said in a statement. "Many have been killed - including women and children, as well as U.N. staff."
The Gaza health ministry said at least 15 people had been killed and some 200 wounded, while Israel Radio said, without citing a source, that most of those killed at the United Nations school were children. (Reporting by Michelle Nichols; Editing by Meredith Mazzilli)
