area. details are thin because of the owe re motorcycleness. we are just getting information this morning we have spoken to several members of the civilian task force ordinary nigerians involved in operations supporting the military. we have spoken to them they are now telling us that a contingent of solders or on their way to investigate what happened. porting allegations that his soldiers were not too far away when the attack took place, 11 they were kilometer as way and didn't heed the call for helpful didn't come to the rescue, we have put that allegations to the military and are awaiting a response. the security the security services including military and police are yet to react to the news. neither has the new revved that came to power on a ticket of fighting boca huh think rah.

he's yet to respond and we are also trying to make contact with the emergency services to find out how they are able to cope with the casualties in such a as i say remote area. >> the fact that three villages were attacked it seems at once doesn't that show that the president's announced goal of bushing back boko haram or breaking down their coordination ability, that's not happening. >> reporter: well, i think the presidency -- the presidency, excuse me, would probably disagree. you know, the new government ado feel that they are making progress and since mohamed took power, just four weeks ago there has been a lot of activity in this vain. he began -- this was even during his inauguration speech by saying that he was moving the command and control center the military's command and control center from the capital abuja so it made no sense for senior personnel to be in the capital

when the fight against boko haram is happening far way in the northeast also ordered that the treasury release $21 million to support soldiers and took the whole issue of boko haram to chad and niger met with leaders there, of course those countries have been affected by boko haram to try to work out a strategy. he also went to the g7 meeting in germany and the african union summit in johannesburg and at the end of this more he will travel to the united states to meet barack obama and it's believed that obviously security in the region will be on the agenda for discussion. so there is a lot of diplomatic activity. one might say sami, that all of this activity going on, obviously the change, and the impact is not being felt on the ground in boko haram are able to launch attacks like this. if the information we were getting about what's happening is accurate. it's a bad sign and it's a sign that clearly more needs to be done to protect is ville saville en

which is what the greeks were very vehemently against months ago. so many of the polls are really too weird and too choppy to call. we have to wait until sunday to have a clear view of what's actually happening. >> let's take the no stair scenario. what happens if greeks vote no? do you think creditors will actually come back to negotiate a new deal which rolls back some of the austerity? >> i think they would have to him the creditors are in a position where they knew at the time that they were investing in risky assets and there has to be accountability for their risk appetite. and so they would have to come back to negotiate. i think the position right now that's being stated is that they won't do that. but greece is a democracy. as far as i know all of the countries within the e.u. are

democracies. so honoring a democratic referendum has to be within the core values of the european union. >> do you think that perhaps for that reason the european creditors are now aiming to bring down the government which is why they don't want to talk before the referendum, even though the greek government in its last proposal almost capitulated to everything that the creditors have asked for? >> sure, i think that's absolutely true. i think they are trying to isolate if the government, i think they are trying to portray them as outsiders and people who can't be negotiated with. and as extremists. the fact is they were democratic i elected in greece. and in the past the e.u. foreign ministers have isolated to keep him out of the discussions and put somebody else in. and so, being, these guys are not going along with the status quo. and they are saying that they have to change the terms of the negotiations. on a very basic level that's

exactly why they were elected. they were electric today change the discussion. so, you know, whether or not you agree with their overall politics, they are definitely trying to find a solution for greece that takes the discussion beyond the status quo discussion. but the status quo discussion for many of the e.u. negotiators is what they want. and the problem is, the status quo discussion doesn't come to a final solution. and it doesn't come to a realistic solution, the greek parliament itself just a week and a half ago said that they absolutely cannot honor the program that his have been put forward by the even u. this is portrayed simply as a series of kind of tsipras type of issue but the overall greek parliament voted for this. so there is a polight you would consensus at the leadership level this is just untenable. do i personally agree with it?

not really. but it is something that the greek government has been mandate today do just months ago in the election. >> thanks so much for your thoughts and analysis there. >> thank you. still come on al jazerra the united states press renews his push to give the country's lowest paid workers a pay raise.
