At least six people have been killed and more than 23 wounded during attacks by US warplanes in Falluja overnight, dispelling any reports of a ceasefire. According to Aljazeera's correspondent, explosions continued throughout the night on Wednesday with the warplanes striking several districts over the city. Hospital officials said the casualties were from the Shuhada, Jolan, Shurta and Askari quarters. Three paramedics were also wounded when US warplanes struck an ambulance which was on its way to assist the injured in the Shurta district. The correspondent further reported that resistance fighters were blaming US forces for breaking the truce, with the US forces blaming the other side. **Baghdad family killed*** A rocket attack blamed on US occupying forces has killed a mother and her two teenage sons north of Baghdad and badly wounded her two daughters, neighbours and hospital officials said. Two rockets slammed into houses in a residential neighbourhood of Baquba, 65km north of the capital, at around 5:00am (01:00 GMT). Walls crumbled, debris was strewn through the homes and a car was destroyed. At Baquba hospital, the family's two daughters lay in a ward, one semi-conscious and both badly wounded. Outside, three coffins were readied to bury the dead. Residents blamed the attack on the US occupying forces. The US Army said it had no immediate information. Local police said they were still trying to find out what happened. "The first hit was just before 5 am," Mahdi Salih said. "The victims were our neighbours, they lost people. Why? It was an innocent house, innocent. The Americans want to harm Iraqis? Why?" **Falluja truce crumbling*** Meanwhile, a 4-day-old truce in Falluja was crumbling amid nightly battles with American helicopter gunships striking on the city. The top US Marines commander in the Falluja area suggested time for negotiations was running out before US occupation forces call off their halt in offensive operations. "I don't forecast that this stalemate will go on for long," said Major General James Mattis, commander of the US miltary's 1st Marine Division. Outside Najaf, 2500 US troops are preparing for a possible assault to capture Shia leader Muqtada al-Sadr. Troops scoured the area around the city, combing through mangroves, villages and the desert in search of al-Sadr's supporters. Meanwhile, two US occupation soldiers were killed in the northern Iraqi cities of Samarra and Mosul in the last 24 hours, a US army spokesman said on Thursday. He gave no other details. **PHOTO CAPTION*** Children have often been victims of occupation attacks. (Al-Jazeera)
