The U.N. Security Council approved a new round of sanctions targeting Iran's nuclear program on Wednesday, sending an "unmistakable message" that Tehran must fulfill its obligations under the nuclear Nonproliferation Treaty (NPT), President Obama said after the vote.

The Obama Administration turned to its attention to foreign affairs this week. The president traveled to Afghanistan to address corruption reform with President Hamid Karzai and hosted French President Nicolas Sarkozy, as both countries pressure Iran over its nuclear program.
