>> reporter: good morning, marah. the latest we're hearing is a u.s. plane has landed deep in the sahara desert. we still have no confirmation of how many hostages escaped from yesterday's operation and how many were killed. certainly, we think six foreign workers were killed. we also are hearing from a local news agency that one of the militants is saying 35 of the hostages were killed. that's unconfirmed. the numbers keep on changing, reflecting how hard it is to get information out of that site, deep in the sahara desert. also, that the situation on the ground keeps on changing. it is ongoing. there are some reports that the militants are still holding on to some of their hostages. the algerian government say they had to act in the way they did yesterday because the islamic militants were threatening to move the hostages. certainly the government didn't consult any of the foreign governments around the world who are concerned about their citizens. the only foreign involvement that we know of is that a u.s. surveillance drone was over the plant. mara
