No nuclear deal with Iran unless actions 'verifiable' - Obama aide

WASHINGTON (Reuters) - Iran must agree to “verifiable action” to satisfy U.S. concerns about its nuclear program or else there will be no final deal, President Barack Obama’s top national security aide said on Monday on the eve of a new round of talks between Iran and world powers in Vienna.

Addressing an Israeli Independence Day celebration in Washington, U.S. national security adviser Susan Rice sought to reassure a pro-Israel audience that Washington would take a tough line with Tehran, despite Israeli worries that the Obama administration is giving up too much in the negotiations.
