promised retaliation for the action in the neighboring mali. >> so remarkable to look back at that footage knowing that was not the only report that was going to happen on that siege. that was just the start and it was going to get way bigger. that was just the first night's report of what ended up being a multiday assault on that gas facility out in the middle of the desert in algeria. in the end the attackers would terrorize and kill 40 of their hostages including 39 foreigners and one algerian. they used guns and mortars and heavy weapons and bombs including bomb belts that they strapped to some of their hostages which is part of what i mean they terrorized and killed their hostages. and that assault, that multiday assault, that happened in january 2013. but that actually brings us right up today with -- right up to date with today's attack. because you saw in that initial "nightly news" news package that the person who was believed to be leading that assault was this guy, mokhtar belmokhtar.
