The Muslim United Army (MUA) is a Pakistani Islamist group responsible for two attacks in 2002 and 2003.  Although the bombings caused only light injuries and damage, proclamations from the group sparked widespread fears amongst Pakistani officials that the MUA was a united front of several Pakistani terrorist groups, such as Lashkar-e-Jhangvi (LeJ) and Harkat-ul-Mujahideen al Aalmi.  <P>  <br /><br />The MUA first emerged in October 2002, when they claimed responsibility for sending several package bombs to police and government buildings in Karachi.  In a series of emails, a man identifying himself as Asif Ramzi, spokesman for the MUA, claimed responsibility for the attack and said the bombings were a warning "to police officers involved in operations against Islamic guerilla fighters at the behest of the Americans."  In another email, Ramzi claimed that "...all the rightwing organizations, including the LeJ have formed the Muslim United Army to organize the groups against the United States."  At the time, Ramzi was thought to be a leader of LeJ, and was wanted by Pakistani police in connection with the murder of American journalist Daniel Pearl in 2001.  Ramzi reportedly died in an explosion in December 2002 while handling explosive materials.    <P><br /><br />On a single day in May 2003, MUA claimed responsibility for 21 small bombings at gas stations in Karachi.  In a statement to the press, the MUA said the attacks were in response to Pakistan's pro-US stance, and the country's continued crackdown on Islamic militants. <P><br /><br />Although bombings and militant activity are common in Pakistan, the actions of the MUA provoked an inordinate amount of fear from Pakistani officials.  The thought that the MUA was actually a united front of Islamic militant groups was a terrifying prospect, and despite Ramzi's death, Pakistani investigators seemed to take his proclamations at face value.  However, MUA has not claimed responsibility for an attack since May 2003, while other groups that were supposedly united have remained independent and active. <br />
