Sari Nusseibeh, the representative of the Palestinians in Jerusalem, said in a telephone interview that Mr. Arafat recognized that attacks like the one in Haifa on Sunday ``will lead to the point of undermining his own authority." But he said that Mr. Arafat ``is not in control" of those who carry them out. And while Mr. Arafat was trying to stop the violence, Dr. Nusseibeh said, he needed to demonstrate to his people that they would gain something from such actions.
