Syria has been labelled 'the most dangerous place in the world'for journalists after Japanese reporter Mika Yamamota was killed amid fighting in Aleppo.
Yamamoto, 45, was an experienced war reporter who had covered conflicts in Afghanistan and Iraq for Japan Press.
Her death brings the total number of journalists killed in Syria in 2012 to 15, according to the Committee to Protect Journalists.
CPJ executive director Joel Simon said: 'We mourn the loss of our colleague Mika Yamamoto and send our deepest condolences to her family and friends.
'Syria has become the most dangerous place in the world for both local and international journalists."
In February, Sunday Times reporter Marie Colvin and French photographer Rémi Ochlik were both killed when their makeshift press centre in Homs was hit by shelling from Syrian forces.
A month earlier Giles Jacquier, a French broadcast reporter, was killed by hostile fire whilst reporting on a rally, also in Homs.
