A large Israeli force launched an attack on the town on the dawn of 21 March, supported by fighter jets. Israel assumed the Jordanian Army would choose to not get involved in the battle, but the latter deployed heavy artillery fire, while the Palestinian irregulars engaged in guerrilla warfare. The Israelis withdrew, or were repulsed, after a day-long battle, having destroyed most of the Karameh camp and taken around 140 PLO members prisoner. The engagement marked the first known deployment of suicide bombers by Palestinian fighters. The battle resulted in the issuance of the United Nations Security Council Resolution 248, which unanimously condemned Israel for violating the cease-fire line and its disproportionate use of force.
