>> against the construction freeze. we think the announcement of new units is a good move forward. but it is minor and to be honest, it is just meant to appease us. some say netanyahu is bowing to pressure but those who document policies say the motion of a construction freeze is wrong. >> we did not see any freezes in the activity h the last year actually, the beginning of 2015, saw an increase in construction, on the ground, we can see that this policy is destroying the possibility for a two state solution. and peace in this area.

sources say the figure is much higher. >> the islamic state have released if i can juries through social media sites they used saying they have killed at least 113 popular mobilization force soldiers. now that's been denied that said they have lost soldiers including members of those militia in the last 24 hours but they say the figures are around 76. there is a propaganda war going on between the iraqis and isil. foe get rid of them, and they are using car bombs to devastating effects now the iraqi security forces have said this will be a decide i operation, and once the cities fall that the whole

province will be back under government control republican hopeful has arrived on the border. a meeting was canceled at request of the group where trump is visiting is mainly hispanic let's for more now from our correspondent hi there, andy, controversy seems to follow donald trump wherever he goes but what is this supposed to achieve. >> i think for donald trump it is about publicity that's what his campaign has been getting he getting attention wherever he goes and it is the same thing here. at the airport the media from all over the world were there to see what this man has to say and what makes this controversial are the comments he just talked about when he said migrants were rapist andle dr.s.

and this morning we went into downtown. lited rally the first people were a brother and sister whose parents came here, and they went on to become citizens themselves, the two children i spoke to both have undergraduate degrees they both said they take offense they said look, they are honest people, they are liking the american dream, they have starts businesses and they are paying their taxes but most people have reacts with eloquence despite how offensive they are to a community but with donald trump who is in considerable lead among the candidates for the republican nomination, this is all about publicity. we aren't sure where he is going, or who will show him around that border now that the union that represents those border agents has din

invited him nevertheless he is a force to be reckoned with. >> andy as you say at the moment he is ahead can that last and it is a novelty factor, who is he appeals to right now. >> it seems like he is unstoppable at the moment, everything he says gets attention, he was seem to sky things that do appeal to a certain type of voter. >> many i have spoken to say they like him because he simply speaks his mind. but remember, there's a long time to go now between that and the republican nomination. but he is now warning that he may run as a third party if he doesn't get the support he wants from the g.o.p. establishment. so that can be a real threat for the republicans with 2016 wrapping up. more and more publicity every day, as every day goes by here.

attract people, they have sort of credibility it's -- it's foundations are very strong so they use this as a front. >> others are taking this idea a stage further he wears it on his shirt he and everybody we spoke to said the way they attack the problem is to defeat people in arguments not to police their ideas on the ground what is the best way of dealing with this is it to try to defeat them in an argument or so go to the police and say they are supporting isil? >> i think the best way is to have a dialog and speak to them face to face, the idea you have to get scholars to defeat the idea so that's one question, but there's a much more fundamental one you know people say if you believe in these things why not go to saudi arabia or somewhere. >> why should we.

we have a good life, yeah, we have a good life. >> you like living here. >> i was born here, my friend. >> one thing is clear the demand that they recognize their britishness, whatever that enmoos isn't going to work. neither side of this culture war shows any sign of backing down. lawrence lee al jazeera. >> the commonly called super bugs bacteria that have become resistant to medication, it is estimated the bugs kill a quarter of a million people every year, and there are warnings that fatalities can jump to 10 million by 2050 if the world fails to develop new drugs. in the first in our series nadine barber met a team which is vying to work out how to beat them.

which have been instructed taken to a patient's arm blood that has been taken from blood. to become resistant. and the strategies for doing that, since as getting people in the bed notes. they have to be concerned about the effected treatment parasites and whether they are resistant to that. equally -- they effect hundreds of millions every year, and it is a major cause of death in children in parts of africa, experts are worried that resistence which

has been increasing in south ease asia, can be repeated in the nations. >> the death rate is very high already, despite the availability of the effected drugs it is already high, so if a drug is not working and there is no replacement drug, handy then will it be a disaster. but that need never happen, as long as the world can share the lessons from the mutations they are finding out about here. >> al jazeera in southern england. >> this again, barack obama will make his first presidential visit to his father's homeland of kenya and while the village isn't on the itinerary locals are hoping the president will change his mind and drop in anyway. they claim the obama name
