later, three men threw hand grenades at passengers waiting to check into a flight to Tel Aviv, killing four and wounding 39. According to Seale, the gunmen had been told the people in civilian clothes at the check-in counter were Israeli pilots returning from a training mission. Austria and Italy had both been involved in trying to arrange peace talks. Sources close to Abu Nidal told Seale that Libyan intelligence had supplied the weapons. The damage to the PLO was enormous, according to Abu Iyad, Arafat's deputy. Most people in the West and even many Arabs could not distinguish between the ANO and Fatah, he said.

The bag had been packed by her Jordanian fiancé Nizar Hindawi, who had said he would join her in Israel where they were to be married. According to Melman, Abu Nidal had recommended Hindawi to Syrian intelligence. Seale writes that the bomb had been manufactured by Abu Nidal's technical committee, who had delivered it to Syrian air force intelligence. It was sent to London in a diplomatic bag and given to Hindawi. According to Seale, it was
