Obama Signs Iran Sanctions Bill Into Law

WASHINGTON — President Barack Obama has signed into law a bill imposing tough new sanctions against Iran over its alleged nuclear weapons program.

The bill Obama signed Thursday evening in an East Room ceremony targets exports of gasoline and other refined petroleum products to Iran. It bans U.S. banks from doing business with foreign banks providing services to Iran's Revolutionary Guard.

The administration hopes the new unilateral sanctions, combined with ones approved last month in the U.N. Security Council, will yield results even though previous regimens failed to halt Iran's activities that could lead to nuclear weapons development.

The U.N. sanctions target the Revolutionary Guard, ballistic missiles and nuclear-related investments.

As lawmakers looked on, Obama called the new law the "toughest sanctions against Iran ever passed by the United States Congress." But he said he had not sought the outcome, contending it was chosen by an Iranian government that for years has defied U.N. resolutions and forged ahead with its nuclear programs while supporting terrorist groups and suppressing the Iranian people.

While insisting the door to diplomacy is still open, Obama said the U.S. is showing the Iranian government that its actions have consequences.

"There should be no doubt. The United States and the international community are determined to prevent Iran from acquiring nuclear weapons," he said.
