An Israeli strike killed 10 Palestinians and wounded at least 20 others on Saturday at a school in Gaza City currently sheltering displaced families, medics said.

Israel pounded central Beirut in a series of strikes, and rockets fired from Lebanon targeted northern and central Israel. The attacks came as the U.S. continues to push for a cease-fire between Israel and Hezbollah.

While Pope Francis has criticized the war before, this is the first time he has publicly suggested an investigation, according to excerpts from a new book.
