Journalists Marie Colvin, Remi Ochlik killed in Syria

Two award-winning journalists — prominent American war correspondent Marie Colvin and French photojournalist Remi Ochlik — were killed Wednesday by Syrian shelling of the opposition stronghold Homs 

The attack, which killed a total of at least 13 people, came as President Bashar Assad's regime escalated its attacks on rebel bases by using helicopter gunships, activists said.
Weeks of withering barrages on the central city of Homs have failed to drive out opposition factions that include rebel soldiers who fled Assad's forces.
Hundreds have died in the siege and the latest deaths further galvanized international pressure on Assad, who appears intent on widening his military crackdowns despite the risk of pushing Syria toward full-scale civil war.
A witness contacted by Reuters from Amman said shells hit a house in the Baba Amr district of Homs in which Colvin, who worked for the U.K.'s Sunday Times newspaper, Ochlik and other journalists were staying and a rocket hit them when they tried to escape.
Syrian activists said French reporter Edith Bouvier of Le Figaro and British photographer Paul Conroy, also of The Sunday Times, were wounded in Wednesday's shelling. Bouvier was said to be in serious condition.
