Ahmad Wail Bakri, a programme director for al-Sharqiya television, was reportedly trying to pass a traffic accident in the Sayyidiyya district on Tuesday when troops allegedly opened fire at his car, according to Riyadh al-Salman, a director of production at the station.
The US military said it had no immediate reports of the incident, but most US military convoys, which are often targets for attack, have signs on the rear vehicles warning drivers and people to keep their distance.
Bakri, who was in his 30s, also worked for al-Iraqiya television, according to his colleagues at both stations. He had been on his way to visit his in-laws at the time of the shooting, al-Salman said.
The French watchdog organisation Reporters Without Borders has called for an investigation into Bakri's death.
More reporters killed
On Sunday, Maha Ibrahim, a news editor with the local Baghdad TV channel, was killed when she was allegedly shot when US troops opened fire after they apparently came under attack in a Baghdad neighbourhood, channel director Saad al-Bayati said.
Ibrahim and her husband were on their way to the station, owned by the Iraqi Islamic party. When asked on Tuesday, the US military had no immediate response.
