Qaddafi loyalists put up fierce resistance in street-by-street defence of Sirte \"We have no morphine,\" said Dr Ezzedine Al Farsi, part of an eight-member team of doctors at the field hospital, a former schoolhouse. \"But we haven\'t needed it much because the snipers are aiming for the heart and the head.\" The casualty toll testifies to the ferocity of the resistance put up by loyalists to the deposed leader Colonel Muammar Qaddafi. At least 22 fighters for the interim National Transitional Council (NTC) were killed and another 155 were wounded on Monday, according to Dr Al Farsi. A day earlier, 25 were killed and 220 wounded, he said. Farag Sheiter, commander of a brigade in charge of the main checkpoint on the eastern entrance of Sirte, said: \"It\'s very different from anything else we\'ve seen. It\'s urban warfare, fighting street by street.\" With no resupply possible, however, their cause is hopeless.
