An Iranian official visiting Egypt said Thursday that Iran and Egypt will work together to resolve Middle East's top crises such as in Iraq, Lebanon and the Palestinian territories, and that both want to upgrade their diplomatic relations, severed nearly three decades ago. But the Egyptians did not comment on the remarks - as they hadn't those the day before by Iranian parliament speaker who said Egypt and Iran would soon restore full ties. Cairo's silence indicated that, despite the flurry of visiting Iranian officials and an apparent thaw between the two states, Egypt expects more than just words from Tehran. The Mideast Sunni powerhouse has always maintained that normal diplomatic relations would come only after the overwhelmingly Shiite Iran stopped meddling in internal affairs of Arab countries. Teheran cut diplomatic ties after Cairo signed a peace agreement with Israel in 1979 and provided asylum for the deposed Iranian Shah Mohammed Reza Pahlavi.
