Thaksin set out to stabilize several problematic areas. One was to launch a major antidrug campaign. Some 2,275 people were killed in a three-month period ending in April 2003, and the government claimed to have eradicated 90 percent of Thailand’s drug problem. In October 2004, the government launched a second antidrug campaign. Another problem confronting the kingdom was terrorist violence, primarily in the south. In 2002 several police officers were killed, bombs were detonated when the minister of interior toured the violence-prone area, and five schools suffered damage from arsonists. The Thai military attributed these actions to a group thought to be an al Qaeda affiliate and arrested suspected members of Jemaah Islamiah (Community of Islam) in June 2003. They confessed to plotting attacks on embassies in Bangkok and tourist sites. Further arsons and bombings occurred, and attacks on police and army bases in 2004 heightened the terrorist threat. In 2004 alone, more than 500 people died as a result of insurgent and terrorist violence in the south. This loss of life was exacerbated when a massive tsunami hit the Andaman coast on December 26, 2004, killing more than 5,300 Thai and foreigners and leaving another 2,900 reported missing.
In February 2005, the Thai Rak Thai won a 75 percent majority in the House of Representatives elections, and, for the first time, a single-party government was formed. Thaksin continued as prime minister.
