Al-Quds city, Feb 27, SPA -- Israeli Prime Minister Ariel Sharon said Sunday that peace efforts with the Palestinians would be frozen if they do not crack down on militant groups in the wake of a suicide bombing that killed four people outside a Tel Aviv nightclub. "There will be no progress politically, and I repeat no political progress, until the Palestinians carry out a determined campaign to destroy the terrorist groups and their infrastructure in the Palestinian territories," Sharon said before his weekly Cabinet meeting. --SPA1140 Local Time 0840 GMT www.spa.gov.sa/242675
