Two journalists, American Marie Colvin and Frenchman Remi Ochlik, were among dozens killed Wednesday as Syrian forces bombarded the rebel city of Homs for the 19th straight day.

Activists have increased calls for a truce to allow humanitarian aid.

According to the Syrian Observatory for Human Rights, the security forces killed at least 68 people across Syria. The overall death toll of violence since March 2011 has reached 7,636.

The Syrian unrest has taken the lives of many journalists, including Colvin and Ochlik.

Let us honor their sacrifices and pay tribute to those journalists who died telling the world the truth of the many atrocities that happen all around the world.
