they responded with tear gas. but rumour has spread around the camp that the boarder had opened. hundreds of refugees ran towards the fence. this woman and her children were sitting around the tent when the resume our reached them. >> like everyone else we ran to the gate. people shouting open the borders. we couldn't see further up. i fell with my kid while running away. this was wrong. we demand our rights. there's no need for violence, we have to be patient and slowly, slowly everyone will get in. >> it was in vain. macedonian forces pushed everyone back. >> it was a disaster in the making. people had been stranded here. some for as long as 10 days. the camp is over congested and the uncertainty among refugees

afghanistan. everyone here lass the same objective to get out of greece as fast as they can. normally they'd take the bus to the boarder. not many are leaving. greek officials say they want toees the pressure. >> a step closer to a new life. they say the only option is to travel north to other countries in europe. the member of the yazidi minority shows me pacts of atrocities he says was committed by i.s.i.l. fighters. beheaded bodies. hour homes have been destroyed. our friend, sons and daughters were slaughtered. we have nowhere to go back to. the stream of refugees is a serious problem. this used to be a transit group. many are stuck.

including in victoria square. it's turned into a temporary camp. most are no longer permitted to across the boarder. >> countries that they are not allowed to across the boarders. they are feeling sad and hopeless. >> the governments await. their struggle to find a home is paused, but not over. every day they are in greece, they remained welcome. >> the u.s. secretary of state says none of the ceasefire violations are significant enough to end the truce. john kerry has been discussing the deal. the pair agreed not to discuss violations in public, and future attacks targetting isil. there are reports of violence in
