Prior to the attack, the Israeli Air Force (IAF) dropped leaflets telling the Jordanian army that Israel had no intention to hurt them, and that they should not intervene; the leaflets went unheeded. "Time" magazine reported the fedayeen had been warned in advance by Egyptian intelligence, and most of the 2,000 Arab commandos who used Karameh as a training base had pulled back into the surrounding hills to snipe at the Israelis. Some 200 guerrillas stayed inside to defend the town. Later, Arafat's deputy, Abu Iyad, claimed in his memoirs that he and Arafat had been tipped off about the Israeli attack by Jordanian officers, who learned it from the CIA.
