UN Secretary General Ban Ki-moon condemned an Israeli strike on a Gaza school that killed 16 people as "unjustifiable" Wednesday, calling for those responsible to be held to account.
"This morning a UN school sheltering thousands of Palestinian families suffered a reprehensible attack," Ban said during a visit to Costa Rica, accusing the Israeli military of ignoring repeated communications on the school's location. "It is unjustifiable, and demands accountability and justice."
