Warplanes have bombed a government clinic in the centre of Falluja as US ground forces engaged in pitched battles with fighters defending the city. Residents said the one-storey Popular Clinic which had been receiving wounded anti-US fighters and civilians was hit overnight as US-led forces pressed into the city. The residents said on Tuesday it was impossible to reach the clinic because of heavy bombing and US tanks in the area. The clinic's telephones were no longer working. An Iraqi journalist, Abu Bakr al-Dulaimi, told Aljazeera that the overnight bombings which continued for more than 10 hours targeted everything in the city including the hospital, houses as well as cars. Al-Dulaimi said the hospital's staff, doctors and patients, have all fallen victim to the assault. He said such fierce bombings have not been witnessed since the Iran-Iraq war.
