The U.S. is studying sanctions against Tehran.

The U.N. Security Council has voted to impose sanctions on Iran. Iran has been accused of supporting terrorism. The Iranian government has denied the charges, saying that the sanctions are aimed at Iran's nuclear program. The vote was voted in favor of sanctions by the UN Security Council. The UN said the sanctions were intended to punish Iran for its nuclear program, which is believed to be linked to al-Qaeda. The US government also said that Iran was responsible for a number of acts of terrorism, including the murder of five Americans in Iran in 2009. The Senate voted in support of sanctions against Tehran on Tuesday, saying they were aimed at the country's nuclear program, which the UN said was linked to al-Qaeda, which has been linked to the deaths of at least four Americans in the past year.
