Palestinian guerrilla leader Yasser Arafat yesterday rejected the Camp David summit as "a dirty deal" and said President Carter would "pay for it."

In a speech to guerrilla trainees at a commando camp at Damour south of Beirut, Arafat hinted that "American interests in the Middle East" would be targets for future attacks, as well as Israel itself.

Arafat, leader of the Palestine Liberation Organization and its main guerrilla group, Fatah, also defied Carter to try to impose the Camp David agreements on the Palestinians.

"I challenge Carter, Begin and Sadat in the name of these fighters here to try to impose their will on the Palestinians," he shouted to cheering guerrilla cadres.

"Camp David is a dirty deal which the Egyptian people will reject and which does not decide our destiny."

Arafat, dressed in olive green fatigues, also said that "Carter will pay for what he signed at Camp David" and that "if they (the Americans) try to hit us once, we will hit them back twice."

The guerrilla chief reserved his toughest and bitterest denunciations for President Sadat, calling him a traitor who "traded a piece of land in the Sinai Desert for Arab Jerusalem."

Arafat's speech came after he witnessed guerrilla "graduation" ceremonies in which new trainees carried out combat exercises with live ammunition and went through an obstacle course.

To back its protest against the Camp David results, the PLO has called for a general strike by Arabs inside Israel and throughout the Arab world. A grouping of Lebanese leftist parties supported the call for a strike in Lebanon, saying Sadat "has signed the final deal of his surrender to the Zionist enemy."

Beirut residents expressed fears that the strike here could lead to more violence if guerrillas try to enforce it with arms. There is also concern that Egyptian government installations could become the targets of new attacks such as those directed at the Egyptian Embassy here when Sadat flew to Jerusalem last year.
