The Fourth Angel (2001) on Netflix

Plot summary

Jack Elgin's family holiday becomes a reporting trip to India, and he brings his wife, Maria, and their three children, Joanne, Julia and Andrew, along. Their AM Air flight makes an unscheduled stop at Limassol in Cyprus, where the August 15th Movement seizes the plane and demands $50 million from the United States State Department within the hour. The demand is met, and the hijackers begin letting the women and children go, leaving the men for last, but when a front passenger door opens a local police team opens fire. Fifteen passengers die, among them Maria, Joanne and Julia, and Jack leaves the plane holding Andrew. In London he learns that the two surviving hijackers were released without charge, and his attempts to find justice by legal means come to nothing.
