Marie Colvin, veteran war reporter for the Sunday Times, was killed this morning with French photojournalist Remi Ochlik when a shell hit a makeshift media centre in the besieged Syrian city of Homs. Two other journalists are reportedly wounded, named as British freelance photographer Paul Conroy, who was working with Colvin, and Edith Bouvier of French newspaper Le Figaro.  Citizen journalist Rami al-Sayed, who streamed live video footage from Homs, was also killed this week in the shelling of the Baba Amr district of the city.
