After failing to meet a July 20 deadline for an agreement on the curbing of Iran's nuclear program, Iran and six other world powers have agreed to extend the deadline four months to Nov. 24. If a deal had been reached, sanctions against Iran would have been lifted and the country would have been allowed access to $2.8 billion in frozen assets. According to U.S. officials, most sanctions would remain in place during the extra four months. "Iran will not get any more money during these four months than it did during the last six months, and the vast majority of its frozen oil revenues will remain inaccessible," U.S. Secretary of State John Kerry in a statement. "We will continue to vigorously enforce the sanctions that remain in place."
