New footage obtained by Reuters shows French photographer Remi Ochlik joking with a group of Syrian Free Army fighters in Homs shortly before a shelling attack.
Later, a building in the Baba Amro district of the city is hit, killing both Ochlik and Sunday Times journalist Marie Colvin.
The amateur video, apparently shot by Syrian rebels, also shows photographer Paul Conroy - Colvin's colleague at the Sunday Times - moments after the fatal attack.
(SOUNDBITE) (English) SUNDAY TIMES PHOTOGRAPHER (MARIE COLVIN'S COLLEAGUE), PAUL CONROY, SAYING:
"When the shelling started, I don't really remember much after that. We had a couple of close hits, and we then took a direct hit somewhere. I was injured in the leg. I think my colleague Marie Colvin is dead, and Remi also is dead, as far as I know. I don't know much at the moment. That's all I can remember. (Off camera question: Do you think Syrian Army intended to hit you?) No, I think they'd been hitting civilians. We were just part of the bigger picture. They have been targeting civilians for 18-20 days. We were unlucky."
Meanwhile, opposition activists say the bombardment of Homs has entered its third week.
This video footage - obtained from a social media website, and which Reuters cannot independently verify - purports to show fierce street fighting between the Free Syrian Army and President Bashar al-Assad's forces.
In a nearby town, a Free Syrian Army officer shows off a tank he says was destroyed during an operation called "Rat Hunt". In a message directed to Russia's Vladimir Putin, he says the burnt tank symbolises the fate of Russian armour sent to Syria.
Russia and China have vetoed U.N. Security Council resolutions calling for a transfer of power from Assad to a deputy.
Both countries are also absent in a major meeting in Tunisia which is aimed at halting the bloodshed in Syria.
