Assailants with rockets and rifles attacked a natural gas plant in a remote tribal region of Pakistan, triggering a shootout that left a woman and her two children dead, a senior government official said Saturday. The woman's home was hit by a rocket late Friday when the militants attacked the main natural gas facility in Sui, about 350 kilometers (215 miles) southeast of Quetta, said Abdul Rauf. He said a gas pipeline also caught fire after it was hit by some rockets, and the security officials deployed there returned fire in the direction from where they believed the rockets were launched. "The exchange of fire continued for hours, and we have no idea whether the terrorists suffered any casualties," he told The Associated Press in a telephone interview.
