ISLAMABAD, PAKISTAN (KYTX/CNN) - The death toll from the strong earthquake that struck southwestern Pakistan this week has risen to 350 as rescue workers struggle to reach victims, authorities said Thursday.
Further complicating relief efforts, two rockets were fired at -- and missed -- a military helicopter on its way to the quake zone. The number of people injured has climbed to 619, said Jan Muhammad Buledi, a spokesman for the government of Balochistan, the province where the quake hit. Authorities estimate that 21,000 houses have been destroyed.
The 7.7-magnitude earthquake took place Tuesday in a remote, sparsely populated area of Balochistan. Rescue efforts are under way in the heavily hit districts of Awaran and Kech. Images from the scene have shown buildings reduced to rubble. More people are feared to be trapped under the wreckage, authorities say, suggesting the death toll could rise. The remoteness of the affected area and damaged communications networks are hindering the rescue operation.
Officials say some areas remain inaccessible, preventing them from getting a full picture of the scale of the damage. Meanwhile, thousands of survivors in need of assistance after the quake are having to cope with high temperatures, a lack of drinking water and little in the way of shelter.
October is the hottest month in Balochistan and the region is in a perpetual state of drought, said Muhammad Hanif, the director of the National Weather Forecasting Center. Temperatures in Awaran and Kech have reached 37 degrees Celsius (99 degrees Fahrenheit).
The Pakistani military has deployed more than 1,000 troops to help with rescue and relief efforts.
