Now that the uprising in Syria has turned into a heavily armed conflict, many in the region are worried that the violence will spread beyond its territory.
Syria borders Iraq, Turkey, Jordan and Israel, as well as Lebanon, where clashes erupted last Friday in the northern coastal city of Tripoli.
Sunni Muslims in one Tripoli neighborhood began protesting against Syrian President Bashar Assad. They put up a huge banner on the side of a mosque that had a picture of Assad, wearing a military uniform, with a big red X across his face.
Syrian troops have fired rockets and mortars at neighborhoods in the city of Homs that have most fiercely resisted the government throughout the uprising.
Mainstream journalists are barred from entering Homs, so a team of activists decided to record the offensive themselves. The activists positioned their cameras atop buildings in the city. Each morning the view is blue sky, a minaret, a sea of rooftops. Then come the booms.
The dispute over Iran's nuclear program has again rocked oil markets. And Iran is threatening to close the Strait of Hormuz, which is just 34 miles wide yet serves as the passageway for 20 percent of the world's oil.
This is not a new drama. In fact, it was a recurring issue in the 1980s. Still, there's been relatively little activity among Gulf oil producers to find alternative routes to get their oil to market.
Today marks a year since an uprising started in the Gulf Nation of Bahrain. And over the course of the year, we saw lots of protests, and we saw the Gulf Cooperation Council send troops into the country to quash the rebellion. We saw the monarchy dismantle the Pearl Roundabout, which had become symbolic of the uprising and later commission a report about what went wrong at the height of the protests last February.
