Muslim terrorist leaders threatened to cut the heads of the pop stars Britney Spears and Madonna if they refuse to convert to Islam, World Net Daily reported.

The threats, recorded on audio, came a day before Madonna arrived in Israel to celebrate the Jewish New Year with fellow Kabbalah practitioners.

"If I meet these whores I will have the honour to be the first one to cut their heads off if they will keep spreading their satanic culture against Islam," said Muhammad Abdel-Al, spokesman and senior leader of the Popular Resistance Committees terror organization.

The Committees, largely based in the Gaza Strip, has carried out thousands of rocket attacks against Jewish population centres and scores of shootings and bombings.

Abdel-Al and other terror leaders were quoted threatening the two music stars in a book, called "Schmoozing with Terrorists: From Hollywood to the Holy Land Jihadists Reveal their Global Plans - to a Jew!," written by WND Jerusalem bureau chief Aaron Klein.
