A BBC team came across a strange vehicle on the way to the Libyan city of Sirte, the scene of intense fighting with Gaddafi loyalists. An old Toyota Landcruiser had been adapted as a gun platform, complete with sliding roof. All photos by Jonathan Head.

The car contains a belt-fed machine gun that rises up through the roof. It has two cameras mounted on it.

The gun is operated by remote control from screens inside.

A fighter from the brigade told the BBC that the vehicle had been found in Sirte and was likely to have been used by one of the Gaddafi family, probably as an escort for an official convoy.

The Landcruiser, which includes this roof hatch, is strikingly sophisticated compared with most of the vehicles the anti-Gaddafi fighters are using.
