A group of "extremist" rabbis (the Sanhedrin, about 70 in number) announced in February that they want Judaism to resume the centuries-ago practice of including animal sacrifices in services and that resumption should start, for historical reasons, in the Jerusalem compound of Temple Mount (but known primarily now as Islam's Al Aqsa Mosque).
According to the rabbis, sacrifice (especially of sheep) was a centerpiece of services in the Old City, but they acknowledge that it is unrealistic to expect current Muslim officials to tolerate the practice. [CNN-AP, 2-28-07]
