The Times of London -- which like Fox is owned by Rupert Murdoch's News Corporation -- backed the Fox version of events in a front-page story Monday.
"The Times and other foreign media effectively became temporary human shields on Sunday night when we agreed to be bussed in by officials to Colonel Gadhafi's main compound in Tripoli to visit the site of an allied missile attack," Deborah Haynes wrote in a story datelined Tripoli.
The paper also cited a government spokesman as saying that "thousands" of civilians were at military facilities and other potential targets. It said another source said some of them were being held against their will.
The incident involved a trip Sunday night arranged by Libyan authorities to the Gadhafi compound that had been bombed earlier by coalition forces.
Robertson said the 40 or so journalists on the bus weren't told ahead of time where they were going, and that there was no attempt by the Libyan minders to restrict anyone from getting on or off the bus before they left.
Upon arrival, the journalists spent about 20 minutes at the damaged building and then were hurried to a tent where they waited with Gadhafi supporters for him to appear, Robertson said. Gadhafi never showed up, and the journalists went back to their bus and departed, according to Robertson.
A government official even pushed him onto the bus as he tried to broadcast a live shot at the end, Robertson said.
"If they wanted to use us as human shields ... they would have kept us there longer," Robertson said. "That's not what happened."
Robertson noted that the sole participant on the trip from Fox wasn't normally a reporter or videographer, but was given a camera and told to go along. In general, Robertson said, the Fox team in Tripoli rarely goes on the reporting trips arranged by the government.
