"Pakistan issued new flood warnings Tuesday as more rains fell and rising water levels threatened to overwhelm one of the country's biggest dams. At least 1,200 people have died so far in the worst flooding to hit Pakistan in generations. Relief work has been hampered by submerged roads, washed out bridges, and downed communication lines, and survivors have complained about government inaction. Other countries, including the U.S., have pledged assistance to Pakistan, which was already struggling to control a rapacious and violent Taliban militant movement. In the northwest, the hardest-hit region, new downpours added to the misery. Rising water levels at Warsak Dam, the country's third biggest, prompted disaster officials to ask residents in the northern outskirts of Peshawar city to leave their homes."
