HARI SREENIVASAN: Rebel fighters in Libya took back a key eight-story building in an urban battle with forces loyal to Moammar Gadhafi. The clashes raged for hours in Misrata, a port city that has seen power shift back and forth over recent weeks.
We have a report from Neil Connery of Independent Television News.
NEIL CONNERY: In the devastated heart of Misrata, Libyan fights Libyan for every foot and every building on every street. These pictures taken by rebel fighters show the close-hand nature of this bitter battle and what it has done to the city.
Footage said to have been filmed over the last two days shows pro-Gadhafi forces still have tanks on the streets. But the rebels claim they are holding their own and even regaining ground. They will be encouraged by the latest American estimates that NATO strikes have destroyed between 30 and 40 percent of Gadhafi's ground forces.
They will also take heart from the presence of U.S. Sen. John McCain in their capital, Benghazi.
SEN. JOHN MCCAIN, R-Ariz.: I believe that we should be much more involved and engaged in the air campaign than we have been.
NEIL CONNERY: It's been confirmed that American Predator drones, unmanned planes armed with powerful missiles, have carried out their first attacks on government military targets. It is an increase in American involvement, but in itself, doesn't change the fact this is looking like a prolonged civil war.
