Alexis Drazen destroys Gaines' staging facility with Semtex
Semtex was a powerful plastic explosive of Czech origin.
During Day 1, after most of Ira Gaines' crew were killed or arrested, Alexis Drazen rigged one of the group's staging areas with Semtex. When Kevin Carroll and the other survivors arrived to prepare for their escape, Drazen detonated the Semtex, killing everyone inside the building and allowing him to stroll out and execute Carroll.
