At least 351 people were killed and nearly 100,000 left homeless when tropical cyclone Nargis tore through Myanmar, razing thousands of buildings and knocking out power lines, state media said Sunday. Residents awoke Sunday to scenes of devastation after the cyclone bore through swathes of southern Myanmar late Friday and Saturday, uprooting trees, cutting phone lines and water pipes, and clogging streets with debris. Myanmar's state channel MRTV said on their Sunday evening news broadcast that 109 people had been killed in Haing Gyi island, just off the coast of southwestern Ayeyawaddy division where the storm first hit. One person was killed in Nyaung Done, a township also in Ayeyawaddy, the channel reported. An information ministry official and state media had already reported that another 222 people had died in Ayeyawaddy, while 19 others were killed in the economic hub Yangon. The authorities have declared disaster zones in the regions of Yangon, Ayeyawaddy, Bago, Mon and Karen states. MRTV said that about 20,000 houses have been destroyed on Haing Gyi island, and 92,706 people there were now homeless. In one mainland township in Ayeyawaddy, 75% of all homes were believed to be destroyed, the channel said, adding that authorities had launched a rescue operation in the region. Nargis made landfall late Friday around the mouth of the Ayeyawaddy (Irrawaddy) river, about 220 kilometers southwest of Yangon, before hitting the country's economic hub. The cyclone brought down power and phone lines, cutting off the military-run nation one week before a crucial referendum on its new constitution
