Islamabad, Pakistan, May 27, SPA -- A well-coordinated attack involving gunmen and an explosives-packed van reduced a police building to rubble in the eastern Pakistani city of Lahore on Wednesday. Amid the confusion and the chaos in Pakistan's second-largest city, various officials offered conflicting casualty counts -- with almost all agreeing that at least 23 were killed. Most were police officers and staffers. The blast also wounded more than 250, with one hospital -- Sir Ganga Ram, itself damaged by the explosion -- alone treating 128 victims. Authorities expected the death toll to rise as rescue workers pick through twisted metal and other debris, looking for more bodies, CNN reported.--SPA www.spa.gov.sa/668635
