Members of the IMU began settling down in the region, with some starting families and becoming involved in local business. The group developed close ties with members of the Taliban and al-Qaeda who had also taken refuge in the region, often serving as bodyguards for senior commanders. Tensions grew with some locals however, with the Uzbeks accused by local Taliban leader Maulvi Nazir of disrespecting local customs, killing tribesmen, and involving themselves in local feuds. In early 2007, fighting broke out between Nazir's fighters and the Uzbeks, which resulted in hundreds of casualties on both sides and the expulsion of the IMU from much of South Waziristan.
