BP rejected claims that the move sought to hide the extent of damage. The company argues that the censorship was only established to provide one reliable source for the public.
Meanwhile, Senior Regional Representative for Sierra Club in New Orleans Jill Mastrototaro said, "It sounds like there's a cone of silence that's been issued on the situation."
"We're very concerned as an environmental organization trying to get the public's voice out there and trying to get access to this critical information," she added.
Meanwhile, journalists and photographers said they had to rely only on information provided by BP, adding that they were not allowed to visit affected areas.
Having eclipsed the 1989 Exxon Valdez spill, the BP oil leak has been labeled the worst environmental catastrophe in the United States.
