Syrian activists have helped to smuggle out of Syria a British photographer, Paul Conroy, who had been trapped in Homs since being wounded there last week. Several activists are reported to have been killed in the operation to get him out of the besieged district of Baba Amr. Jim Muir reports from Beirut.
Paul Conroy left Baba Amr during the day yesterday. He was smuggled across the border into Lebanon in the middle of the night and taken to Beirut, where he's resting after his ordeal. He was wounded in shelling last Wednesday that killed his colleague Marie Colvin of the Sunday Times and a French photo journalist, Remi Ochlik. But his wounds are relatively light. An activist who helped smuggle him across the border said he was able to walk, was in good health and good spirits. There are conflicting reports about what's happened to the other wounded journalist Edith Bouvier. She's more seriously hurt and needs to be carried on a stretcher. Reports that she too has crossed the border into Lebanon have not been fully confirmed.
Polls have opened in the latest Republican Party primaries in the United States. Voters in Michigan and Arizona are choosing who they want to challenge President Obama in November's election. In Arizona, Mitt Romney is expected to win comfortably, but Rick Santorum has mounted a strong challenge to him in Michigan. Paul Adams reports from Washington.
Of the two contests today, all eyes are on Michigan. A few weeks ago, this would have been unthinkable: Mitt Romney grew up there, and his father was the governor. But Rick Santorum's victories in three states earlier this month energised his campaign and shattered the notion that Mitt Romney might wrap up the nomination quickly. If the more socially conservative Mr Santorum wins in Michigan and even if it's close, then it'll be clear that this contest is far from over.
