We formulate a method to compute breakup processes of three-body halo systems reacting with a target. The reaction between one of the particles and the target as well as the corresponding pairwise final-state interactions are carefully treated. Both absorption and diffraction processes are included. Detailed differential and total cross-sections are calculated for two-neutron (2n) removal from 6He by fragmentation on 12C. The physically motivated core shadowing is phenomenologically included. We obtain good agreement with available experimental momentum distribution data.
