Chagai-I

Chagai-I is the code name of five simultaneous underground nuclear tests conducted by Pakistan on 28 May 1998 at 15:15 PKT. The tests were performed at Ras Koh Hills in the Chagai District of Balochistan Province. Chagai-I was Pakistan's first public test of nuclear weapons. Its timing was a direct response to India's second nuclear test Pokhran-II, on 11 and 13 May 1998. These tests by Pakistan and India resulted in United Nations Security Council Resolution 1172 and economic sanctions on both states by a number of major powers, particularly the United States and Japan. By testing nuclear devices, Pakistan became the seventh country to publicly test nuclear weapons. Pakistan's second nuclear test, Chagai-II, followed on 30 May 1998. 28 May, the day of the nuclear test, is referred to as Youm-e-Takbir in Pakistan; it is celebrated as a national holiday commemorating Pakistan's emergence as a nuclear power.
