KARACHI/LAHORE (Agencies) Another four days of torrential downpours have been forecasted while incessant rains across the country have killed dozens of people, damaged properties and destroyed crops on large areas. Five districts in Sindh have been declared calamity-hit, while rains have wreaked havoc in many areas in Balochistan, Khyber Pakhtunkhwa and Punjab. Heavy rains battered vast swathes of the countryside in Sindh during the first three days of Eid, killing dozens of people, breaching canals and flooding vast stretches of farmland. The spell came as a bolt from the blue for the countless still living in makeshift shelters after last years unprecedented floods rendered them homeless. The recent floods have reportedly affected 400,000 homes, and over 150,000 people have been shifted to relief camps. Breaches developed in two canals in Khairpur district on Saturday inundating a large number of villages and standing crops. The metrological department has forecast more rains throughout the province that would continue for another four days, setting for fears of heavy loss of infrastructure in cities and cotton and other field crops in rural areas. President Asif Ali Zardari has sought report of rescue works in flood-hit areas while NDMA has distributed ration bags in the effected areas. President Zardari has directed to speed up rescue work in the flood-hit areas of Sindh while Premier Yousuf Raza Gilani directed to send further ration bags and tents in affected areas. According an NDMA spokesman, 18,000 tents and 40,000 ration bags have been sent to flood-hit areas. On directives of the PM, NDMA has sent 10,000 ration bags to Shaheed Benazir Abad. NDMA Chairman Zafar Qadir told a private TV channel on Saturday that the government of Sindh has formed separate teams to ascertain reasons behind the devastated flood and estimating damages caused by the torrential rains. More rains are also being predicted in Balochistan, Khyber Pakhtunkhwa and Punjab, where more rains prediction and possibility of flood in river Sutlej have multiplied the worries of the people residing in low-lying areas. According to Pakistan Meteorological Department, a medium-level flood is expected in river Indus near Attock, and in Sutlej and Beas rivers on the Indian side which may flood the Pakistani territory. Chief Meteorologist Muhammad Riaz, at the Lahore Flood Warning Centre, said that threat of flood was looming over Ganga Singh Wala and Head Sulemanki. He said that rains in Khyber Pakhtunkhwa could flood the area between Attock and Sindh. Also, a new monsoon system in India may bring heavy rains with thunderstorm in various districts of interior Sindh and Punjab, the met office said. The experts were of the view that current rains were harmful for cotton crops in southern Punjab and Sindh that could result in decrease in cotton production and increase in its prices. Any harm to cotton production would ultimately hurt the textile sector which was already in the grip of number of crises due to energy shortage and textile exports could be almost reduced to 50 percent, the experts said. In Balochistan, torrential rains have wreaked havoc in Nasirabad, Jaffarabad, Osta Muhammad, Suhbat Pur, Dera Alla Yar, Dera Murad Jamali, Tambu, Manjho Shori, Baba Kot, Rojhan Jamali and other villages. The safety bridge in Muzaffargarh has broken due to which the standing crops on 4,000 acre have been destroyed.
