The latest U.S.-Iran talks on Tehran's rapidly advancing nuclear program will not take place Sunday, mediator Oman said Saturday, as Israel and Iran traded blows a day after Israel's blistering attack on Iranian nuclear and military sites.

Experts suggest the U.S. has a strategic opportunity to leverage Iran's weakened position for a nuclear deal after Israel's targeted strikes on Iranian nuclear and military sites.
