U.S. top diplomat Antony Blinken made an unannounced visit to the occupied West Bank on Sunday, where Palestinian President Mahmoud Abbas urged him to persuade Israel to agree to a ceasefire as more died in a strike on a refugee camp overnight. A spokesman for the health ministry in the Hamas-run Gaza Strip said earlier on Sunday that Israeli military had struck the Maghazi refugee camp overnight, killing at least 47 people. In a separate attack, 21 Palestinians from one family, including women and children, were killed in Israeli strikes targeting Gaza overnight, the health ministry said.
