Israeli warplanes pounded the Gaza Strip overnight and into Wednesday morning—despite reports of a ceasefire—after a Palestinian rocket was fired toward the Israeli city of Ashkelon. Both Hamas and Islamic Jihad denied responsibility for the rocket fire, saying it was an “individual act.” Meanwhile, Israeli forces shot and killed an 18-year-old Palestinian in the West Bank during an arrest raid in a refugee camp near Bethlehem.

The latest violence came as Israeli Prime Minister Benjamin Netanyahu returned to Israel early from a trip to the U.S. where he met President Trump at the White House and welcomed both Republican and Democratic lawmakers to the annual conference of AIPAC—the American Israel Public Affairs Committee.
