In response to persistent PLO raids against Israeli civilian targets, Israel attacked the town of Karameh, Jordan, the site of a major PLO camp. The goal of the invasion was to destroy Karameh camp and capture Yasser Arafat in reprisal for the attacks by the PLO against Israeli civilians, which culminated in an Israeli school bus hitting a mine in the Negev, killing two children. However, plans for the two operations were prepared in 1967, one year before the bus attack. The size of the Israeli forces entering Karameh made the Jordanians assume that Israel was also planning to occupy the eastern bank of the Jordan River, including the Balqa Governorate, to create a situation similar to the Golan Heights, which Israel had captured just 10 months prior, to be used a bargaining chip. Israel assumed that the Jordanian Army would ignore the invasion, but the latter fought alongside the Palestinians, opening heavy fire that inflicted losses upon the Israeli forces. This engagement marked the first known deployment of suicide bombers by Palestinian forces. The Israelis were repelled at the end of a day's battle, having destroyed most of the Karameh camp and taken around 141 PLO prisoners. Both sides declared victory. On a tactical level, the battle went in Israel's favor and the destruction of the Karameh camp was achieved. However, the relatively high casualties were a considerable surprise for the Israel Defense Forces and was stunning to the Israelis. Although the Palestinians were not victorious on their own, King Hussein let the Palestinians take credit. Some have alleged that Arafat himself was on the battlefield, but the details of his involvement are unclear. However, his allies–as well as Israeli intelligence–confirm that he urged his men throughout the battle to hold their ground and continue fighting.
