(CNN) - Heavy gunfire reverberated in central Cairo before dawn Thursday as supporters and foes of embattled Egyptian President Hosni Mubarak continued to face off at Tahrir Square, where chunks of concretes and Molotov cocktails were employed as weapons in the escalating crisis. CNN personnel saw wounded people being carried into Tahrir Square, largely held by anti-regime demonstrators, through an entrance that leads to the nearby Egyptian Museum. Several ambulances entered and left the square shortly before 4 a.m. Thursday. Sustained automatic weapons fire, including from what sounded like a heavy machine gun, echoed around the square, the epicenter of nine days of protests calling for Mubarak's ouster. Anti-government demonstrators hunkered down behind makeshift barricades in the square and outside the nearby national museum against the onslaught, which demonstrators said included plainclothes police officers.
