ukrainian vessels capturing the crew twelve ukrainians have now been charged with unlawfully entering russia they face up to six years in jail but russian president vladimir putin blames the ukrainian president for the standoff claiming it's a move to boost his ratings it was just a little it's clearly a product of. a provocation. and i think it was the president himself should head of the presidential election to be hideous in ukraine just. what is this additional international pressure against russia is building with talk of further sanctions u.s. president donald trump has threatened to cancel a meeting shared jeweled with president putin at this week's g. twenty summit. meanwhile ukrainians are preparing for a new phase of war with the conflict showing no signs of stopping. well i'm joined now by correspondent david. and he is in the ukrainian capital kiev good evening to

you david we have these ukrainian border regions about ten of them that are under martial law now and there are reports of increased russian military activity at the border what are you hearing well yes it should be said it's martial law or maybe a better word for it would be war footing it's preparation for what the president has said could be a full scale war with russia as we heard in the report we are hearing of course that there is a build up along the borders this is what the president has said and the russians the interfax news agency said that there's a a s four hundred missile system that has been added to those that are already there three that are already on the crimean peninsula so obviously the tensions are rising the. the fear obviously and here in ukraine is that this could lead to something much larger but at the moment of course nothing like that is happening and what more do we know about lose

ukrainian sailors who are being held and president putin's accusation that the ukrainian boats were also carrying ukrainian spawn's. well yes. the krooman have been all sentenced to two months of pretrial detention but of course the larger picture of that is that this is a really a pawn they're really pawns between the two governments the mr putin's accusations obviously have. raised a great deal of attention but it should be said that the tensions between ukraine and russia have been rising for a great a long time now since two thousand and fourteen ever since russia annexed the crimean peninsula and in the sea of azoff so actually it shouldn't be of any surprise that there are intelligence agents on either side it should be said in the in the hours of sea or wherever else they might be coming into contact and what

about. to solve this crisis diplomatically well those are going nowhere at the moment we heard about president trump who sent sort of mixed messages but at the moment is discussing possibly not meeting with mr putin on the sidelines of the g. twenty summit otherwise the the ukrainians have been good have received a great deal of support from their western partners there's talks of increased sanctions there's also talks about there's been a demand from the e.u. to allow free access to the as i see which is actually what the ukrainians and the russians have had in place since two thousand and three but at the same time nothing between russia and ukraine a phone call from mr partial to mr putin was recently rebuffed. or correspondent david stern in the story corps in kiev tonight david thank you well here's some of the other stories now that are making headlines around the world
