American war correspondent Marie Colvin was deliberately targeted and killed by artillery fire in 2012 at the direction of senior Syrian military officers seeking to silence her reporting on civilian casualties in the besieged city of Homs, according to a civil lawsuit filed Saturday on behalf of her sister and other heirs.

Based on information from high-level defectors and captured government documents, the 32-page complaint alleges that the military was able to electronically intercept Colvin’s communications from a clandestine media center operating out of an apartment in the densely populated Baba Amr neighborhood in Homs. Syrian officials paired the intercepts with detailed information from a female informant to pinpoint the location of the reporter who worked for the Sunday Times of London.
