Two major fronts at the annual nato summit in wales. Leaders say they are building a coalition of nations to take on the threat of isis in iraq and in syria. The leaders also came down hard on rushia for supporting rebels in eastern ukraine. Senior International CorrespondentNic Robertson has our report. Concern here from nato leaders that while there is a ceasefire agreed in ukraine, that this hey not become a reality as the peace is implemented. They note from the statement over president poroshenko here that important for him in his 12step plan is the independence territorial integrity and sovereignty of ukraine. That is something that the leaders here say wasnt present in what president putin had talked about in his sevenpoint plan for peace, that he had talked about a cessation of who is at this times, a removal of Ukrainian Forces from the southeast of ukraine, essentially ceding territory to the prorussian rebels annexation of that area. That according to the nato leaders here is not satisfactory. So a certain level of skepticism as they will watch this play out and intent they say to continue with economic sanctions against russia and the announcements that theyve made here about this new Rapid Reaction force intended to send a clear message to russia. That they will stand behind nato nations should this sort of situation develop in their countries. This is how Prime Minister british Prime MinisterDavid Cameron explained how this how this Rapid Reaction force would work. Weve also agreed to step up natos ability to respond quickly to any threat with a new multiempty national Spearhead Force which is deployable anywhere in the world within two to five days. Ukraine not the only issue here at the nato summit. A lot of discussion in the about isis, the threat they pose to the west. President obama outlining some of the discussions that have been held, discussions between the United States, australia, canada, denmark, france, yaerm, italy, poland, turkey, britain. All of those nations, ten nations involved in discussions about how to combat the threat of isis, how to squeeze down the area theyre operating in and then hip dismantle and destroy that jihadist organization. The idea, the summit here was to discuss how those different nato nations could contribute, an idea for sharing intelligence for thwarting isiss ability to raise funds, their financing to monitor the borders more closely, to support the nations in the region that are battling against isis to support those nations that are helping support the new and emerging Iraqi Government. President obama also located out some fresh details of how helping and working with sunni tribes in the region could can be very key to defeating isis. I think it is absolutely critical that we have arab states and specifically sunni majority states that are rejecting the kind of extremist anihilism that were seeing out of isil, that say that that is not what isil is about and are prepared to join us actively in the fight. The message from alt leaders on those core issues that were discussed here, ukraine and tackling isis. Are you speaking with a united, strong voice to send a clear message not only to president putin in russia but also a clear message of intent of how they plan to deal with isis and the threat it poses to the nato nations in the coming weeks and months ahead. Nick robertson, cnn, newport, wales. Now as of this point we are about 16 hours into the ceasefire in ukraine. And from all accounts, it appears to be holding. So many western countries are skeptical about this ceasefire. Are these sides any closer to seeing eye to eye on the future of that region . Reporter i think when it comes to the big issues, the cor core demands that have caused this impasse, they havent addressed them yet, but the ceasefire seems to be holding, and that is significant because presumably its going to set the stage for these sides to tackle those issues. The ceasefire went into effect 6 00 last night. It is a little after 10 00 kiev time. When the ceasefire went into effect there were some reports of explosions and shellings in southeastern ukraine. Its not clear if the explosions and the shelling happened right before the ceasefire went into effect or right after, but whatever the case, since that time, no reports of fighting during the overnight hours. This agreement was signed yesterday in the city of mensk, belarus. First it was the prorussian rebel leaders who confirmed that the agreement had been signed. Then it was pet row poroshenko. He struck a very conciliatory tone. That human life was the highest value and his aim was to end the bloodshed. He also hopes these talks will lead to more substantial negotiations about the core issues, and he said this is going to be a 12point plan. Whats been frustrating is that we still havent been clear on what the 12 conditions, the 12 points are, but we do know among the conditions are obviously an end to the fighting in southeastern ukraine, the pulling out of heavy weapons, the exchanging of soldiers who have been captured during the conflict. And that could happen as early as today, the establishment of the humanitarian corridor where people can leave the area, and humanitarian aid can come in. That can happen today as well and the positioning of international monitors to make sure all sides are meeting these conditions. So now we watch closely the conflict zone to see if these two sides continue to heed this ceasefire agreement, but at this point, george, it looks like theres finally a pause to a conflict that led to the killing of more than 2500 people, injury of more than 10,000 people, 1 Million People displaced. So a muchneeded pause in this conflict seems to be here, george. So the ceasefire seems to be holding at this point. Reza, we appreciate your reporting. Now to isis and kurdish troops in iraq. Cnn was the only News Media Organization on the front lines. And our anna coren followed along with person merg ga forces. Reporter on a dirt road, a long convoy of peshmerga head toward enemy territory. Theyre gearing up for a Major Mission to eradicate isis across a 30 kilometer front.

At dawn the offensive begins. A barrage of heavy weapons raining down on isis from multiple positions. And these heavy plumes of smoke the result of u. S. Air strikes. These islamic extremists sooef seized control of this area back in june. After the advance across iraq.

According to the person mer fwa, they have gillkilled a number o militants. This doctor is normally based in baghdad. He knows they need him now more than ever. This is a duty of everybody who wants democracy and freedom and human rights. Reporter but while the kurds are looking to create a bigger buffer around their capital, they are positioning themselves to when they could take part in a move within mosul. Weve been taken to one of the villages reclaimed in recent weeks, now less than 2 kilometers from the fighting. This is what the fight against isis looks like. The peshmerga taking avillage after village with the help of u. S. Air strikes. This is the aim for president obama, degrade and destroy isis. A hard and bloody task according to these soldiers. If youre not careful they will get you and shoot you. You have to be very careful. Reporter but during this assault it was the peshmerga who sustained fewer injuries. A number of isis fighters were killed and a number captured. A victory they know wont always be easy in the days ahead. A u. S.

We have helicopters trying to fly in there and plucking people off from rooftops. That is the situation in pakistan and in portioning of india. And the problem is that theyre doing those rescue efforts with more heavy rain. And when you get that heavy rain, that reduces the visibility. So the helicopters cant fly. And people have to just wait and sometimes you wait too long and the water goes over the rooftops, and its just a terrible situation. And more rain is going to be on the way. Look at the blow of thunderstorm activity here. An unusual pattern because by now we should have the monsoon withdraw, but they have not. They got three times their Monthly Average. Things should be winding down, but theyre not. Thailand has also seen very heavy rainfall the last 24 to 48 hours. 58 millimeters here, 195 millimeters here.
