The troubled relationship between Iran and the International Atomic Energy Agency doesn't appear to be getting any better.
Back in February, senior agency delegations traveled twice to Iran to clarify its concerns about possible nuclear weapons work.
And on Monday, the head of the IAEA, Yukiya Amano, said Iran is not providing the necessary cooperation that would allow the agency to give credible assurances that Iran's nuclear work is entirely peaceful.
The White House meeting next Monday between President Obama and Israeli Prime Minister Benjamin Netanyahu could be the most critical encounter for the two men since they took office.
Netanyahu is expected to argue that time is running out on efforts to discourage Iran from developing a nuclear weapon. Obama may say the Israelis can count on U.S. support, but that they should give sanctions and diplomacy time to work before turning to military action.
A key rebel stronghold in the central Syrian city of Homs has fallen to the Syrian army.
Residents fled as government forces bombarded the city's Baba Amr neighborhood for nearly a month. On Thursday, the rebels withdrew.
When the Syrian uprising began nearly a year ago, Baba Amr saw regular, daily protests. Then after months of being shot, detained and tortured, protesters began taking up arms. Those armed civilians were later joined by defectors from the Syrian military, and together, they called themselves the Free Syrian Army.
