they put out a buffer zone which at the moment is being discussed as a cease-fire and then sort out the difference. and the fact that the libyan government played host to the envoy even though his position very different from theirs i think is very telling. and the fact that libyans were telling us that they were the ones who invited that envoy. and i think perhaps gives people a little bit of hope that we are moving towards a place in spite of the hostilities on going in the east whether the libyan government is seeking to try to find a political way through this. >> are we seeing, i guess, a different phase now of this offensive taking place now? on the one hand we spoke there of the oil minister reportedly defecting, although, we don't know where he is. and now there are reports that gadhafi is using another type of mortar. is there a sense he is upping the ante now?
