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.
Iran holds parliamentary elections on Friday, the first since the disputed, and many believe fraudulent, presidential election in 2009.
But unlike that presidential poll, candidates seeking to take on the country's conservative rulers will not be taking part Friday; they are mostly under house arrest or have been in prison for years now.
The focus will be on which conservatives end up on top and how many votes are cast.
