An explosion in Tehran Wednesday killed an Iranian nuclear scientist while he was driving his car. It's the fifth such death in five years, and Iranian officials immediately blamed Israel. The attack is the latest manifestation of escalating tensions between Iran and the West.

A defiant Bashar Assad addressed the nation for the first time in seven months Tuesday, making clear he has no intention of halting the violent crackdown on anti-government protesters and renegade soldiers. Assad lashed out at the Arab League, which has deployed monitors in Syria to oversee implementation of a peace plan. Two of those monitors were reported lightly wounded Tuesday in an attack near a northwestern city.

Syrian officials are vowing to respond with an iron fist to a suicide bombing in Damascus today, 25 people were killed. It was the second deadly bomb attack in the Syrian capital in recent weeks. The government and opposition activists traded accusations as to who was responsible. And the bombing raised fears of escalating violence, as the Arab League presses Syria to implement a peace plan.

NPR's Peter Kenyon is monitoring developments in Syria from Istanbul.

The year began on a note of cautious optimism on the Iran nuclear front. But talks in Geneva and Istanbul proved inconclusive, and the Arab Spring uprisings soon pushed Iran off center stage. And as 2012 approaches, observers see little reason for optimism regarding a diplomatic solution to the Iran nuclear dispute.

Iranian President Mahmoud Ahmadinejad, under attack from other conservative factions at home, continues to find a safe rhetorical haven in defending Iran's nuclear program — and in attacking the U.N. nuclear watchdog, the International Atomic Energy Agency.

As he prepares for the midday rush, Mustafa Baljan puts the finishing touches on the kebabs, salads and stews that make up many a working Turk's lunch. As the steam carries the scent of lamb and garlic into the street, the 37-year-old restaurant owner considers a popular question: With European economies on the ropes, should Turkey still be seeking to join the European Union?

"Are you kidding? Of course I don't want to join," Baljan says. "Countries are going bankrupt. Why would we want to join a union like that?"

Some Americans are old enough to remember pulling up to the pump at gas stations advertising fuel in cents per gallon, not dollars. For many Libyans, that's the way it has always been and should continue to be in this sparsely populated oil-producing country.

At a Tripoli gas station on a recent afternoon, popular opinion among local Libyans appears to be that the government would keep the prices low, around 60 cents a gallon, or bring them down even further.

In the new Libya, uncertainty is the one certainty.

Contradictions and conspiracies proliferate faster than street demonstrations now that the iron fist of dictator Moammar Gadhafi's regime has been lifted.

Among those searching for answers are relatives of prisoners locked away by various revolutionary military councils. Some of the prisoners are former Gadhafi loyalists with blood on their hands. But family members say others were seized for motives of revenge.
