minsk results and without explanation because unfortunately after minsk the defense operation of russia intensified significantly. >> reporter: so where is the fighting in eastern ukraine taking place as the clock ticks down to the ceasefire deadline? these are the areas currently held by the separatists fighters and seen shelling after ceasefire deal announced and also reports of shelling and live fire in the rebel held town of luhansk and the main battle seems to be for control of strategic importance as a rail way town linking the two main rebel strongholds to russia and government forces currently hold it but are under intense fire. and military analyst at the institute for golf military and says this is a decisive moment in the ukrainian conflict. >> i think it's very clear that the russians who are supporting

the separatists are trying to take the strategic location almost immediately and if they do not do it by the deadline tonight for the ceasefire they will continue to do it tomorrow and then we are going to see the minsk two process begin to unrival. i think from there it's going to be a mix of diplomatic pressure from both sides, obviously more from the russian side in terms of that mix. having said that the united states canada and great britain will likely begin to push for lethal aid to kiev while at the same time the ukrainian government and ukraine itself is slipping deeper into bankruptcy. i think that this is going to lead to some more confrontations in the field as well as whether or not the kiev government can receive the kind of assistance it needs from europe and from

the united states because there is an rubicon to be crossed here that i think will shift it up into a new level of confrontation. >> reporter: the u.n. special envy to syria clarified an earlier remark that president bashar al-assad musts must be part of the solution and staffan de mistura says he wasn't talking long-term solution but efforts to end the fighting and gerald ton has more. >> reporter: destruction are clear signs that talks have broken down. rebels in homs say they won't accept government demands to lay down their arms in exchange for civilian safety so the fighting continues in syria. >> translator: why isn't anyone caring for us? we suffer in silence while the whole world watches. world powers still trying to negotiate an end to the

u.s. invasion of iraq. that's the point where the sectarian project in the region really began. and once the iraq war was over as far as the military damage and the u.s. damage and military the intervention then that moved lebanon and syria and it was manifested within what came to be the assassination. >> reporter: the loss of a strong city leader had a direct impact on the sunni community and failure of a successor and coupled with what happened in the region solidified sectarian divisions and made some identify with more radical groups poverty also plays a role like in the northern city of tripoli where the syrian war is having a direct impact. there have been street battles between those who support the revolution and those who support president bashar al-assad and many will tell you the increasing violence and divisions here come down to the state and more specifically the politicians not doing enough to take care of their people. >> we have a system that is

collapsing or at least that is degenerating and deteriorating, this is a problem but been there and building up since the 1990s the difference now however is the influx of a massive number of syrian refugees now forming anywhere between one quarter and one-third of the lebanese population. in a system that already was failing to deliver services to its own citizens. >> reporter: security has become a huge issue with the army along with the armed shia group patrolling the border areas and attacks inside lebanon against sierra neighborhoods associated with hezbollah and i ran for retaliation of fighting and along bashar al-assad and after they were killed downtown beirut and few predicted where they find themselves now and foreign countries have too much say of what happened here a

attacked people living in the delta and destroy oil pipelines and kidnap foreigners. after years of fighting in the creeks former war lord pastor rubin lives a comfortable life largely financed by amnesty program and one he doesn't want to give up and knows it could happen if president good luck jonathan loses the election in march. >> and if for any reason people who are desperate of power win the election and push good luck jonathan out of villa, there will be no peace in the villa and and go back. >> reporter: this is how people live and poverty and frustration can make it easier forward lords to find new recruits and believes the government's amnesty was only a short-term solution that benefitted only a few. >> so if you didn't carry arms

then you didn't qualify for amnesty so the question is the people who have potential to carry arms that have not carried arms what do you do with them? they are the ones that are left out and they are the ones that will carry arms in the future. >> reporter: struggling single mother says if things get worse she will join any war lord who offers her a way out of ofpoverty, in the delta. hundreds more migrants rescued from the over crowded boats off the coast of libya and cargo ship and italian vessel rescued 700 migrants after hearing a distress and they have been taken to sicily and another country and several drown trying to reach italy from north africa. ten years ago three young americans registered a website domain name with the idea of
