is you can look at this terrorist group is a new terror threat international debut. up until this point they've been domestic threats and smaller attacks outside of the country and even a dispute within the leadership about where they should focus resources. should they take an international impact and here it looks like that latter group is there. drawing on experience of tmumba attack. >> tremendous tv and newspaper and anything on the internet. zain, let me ask you, is there contact with any of those in the building? do we know that terrorists are still in there because some people who haven't come out? any negotiations at all?
