From today's New York Times:
Paul McCartney has refused to cancel his concert in Israel, despite threats from Islamic militants, the Israeli newspaper Haaretz reported. The response follows comments made by Omar Bakri Muhammad, a militant Lebanese Islamic activist, in an interview that appeared in The Sunday Express of London. Mr. Bakri said, “If he values his life, Mr. McCartney must not come to Israel,” He also said: “He will not be safe there. The sacrifice operatives will be waiting for him.”
Omar, dude -- "Silly Love Songs" was thirty-five years ago. Move on.
