this behind them as they focus on the nuclear negotiation. obviously the united states is more concerned with isil and they would like this to stop as well. so i do think there is hope if the houthis basically with, you know, with backing from iran or pressure from iran stop violating the east fire. south korea's intelligence services say that north korea's defense minister has been executed. they say that the chief of north korea's armed forces was killed by fire squad. he's believed to be the latest in a series of senior officials executed this year. kerry brown is from the china studies center at sydney university he says this purge may be an indication that kim jong-un's regime is unsustainable. >> it's been quite common in the whole history of, you know, the democratic people's republic of

regime is sustainable. the problem is, that they don't really have a plan-b. there is no plan-b. they either sink or swim together and it seems that kim jong-un is really willing to basically kind of totally throw these people away if they get on the wrong side of him. very very you know, kind the categorical. malaysia security officials are due to meet wednesday to discuss the surge of row rohingya and bangladesh i refugees. malaysia says it will turn away boats carrying migrants unless they are in danger of sinking and i indonesia says it will not allow the boats to enter its waters many row hen ga migrants are being detained and we have this update. >> reporter: hundreds of migrants are being processed. here after arriving on boats earlier this week. these migrants need to be moved to detention facilities on the

mainland. but we are hearing that these facilities are already overwhelmed by the number of people they are being asked to accommodate. a senior maritime official told us that they will not be allowing anymore of these crowded vessels to enter malaysian waters. unless they are in distress. now, this has generated sharp reactions from human rights activists here in malaysia, they say they are shocked to hear about this policy. and that it's tantamount to signing the death warrants of potentially thousands of desperate and very poor migrants that could still be out at sea. >> so how do the rohingya end up in malaysia. their journeys often begin in myanmar. in the past they used to escape by crossing overlapped through thailand. since thailand began a crack town migrant advocates say the rohingya have been terrificked to indonesia and malaysia. a report now from southern

agreement among all of the nato members that this is a critical motionmoment for action by russia, by the separatists to live up to the minsk agreement. and that it is critical to be able to get the o.s.c.e. in to areas of conflict. it is important to end the conflict in those areas particularly they need to try to come to an agreement on a ceasefire. >> imran kahn joined us now from there. imran, kersey there trying to indicate unity with nato. we know that's not the case, especially when it comes to ukraine. >> reporter: that's absolutely right. nato has been criticized from within it's own 27 members particularly the eastern european countries of not doing enough when it came to ukraine of not getting the minute of course agreement to be signed by all of its members, although it was a very positive message, one of unity from the secretary of

state, john kerry backstage we are still seeing those divisions. a lot of diplomacy still be done here and talking about how exactly they can move forward. but this was a very public show of support that nato was unified. however, as we know those divisions still remain and ukraine still remain a big issue for nato. >> i am wondering what else was discussed and what the focus is now? >> reporter: well, iran was discusses. secretary kerry saying the diplomacy was being ratcheted up. afghanistan key, nato reaffirming their commitment to their roll within afghanistan also syria was discusses but syria was only mentioned by name name. no plan given. they have trying to push for the idea of secure zones within syria, secretary of state john kerry didn't mention those secure zones didn't mention any kind of nato roll in syria.

now nato is stretched with its commitments in afghanistan and other places it doesn't need anotherrish on you its plate. but this seems to be being pushed by turk any particular and some of the other members of nato. so syria also remains an issue that nato needs to talk about today. now, american diplomacy, i have to say is being stretched. the secretary of state is leaving here and he's flying to camp david where the gulf corporation council is meet to go talk about yemen and he was very apologetic for that he said i would love to say here is and discuss all these issues but we have other pressing problems with yemen and the g.c.c. meeting. it seems that american diplomacy is being stretched very thin at the moment. >> thank you imran. it's now just over 24 hours since a seven-point flee magnitude aftershock hit nepal and the scale of the damage is being abouting clearer. 65 people are confirmed to have been killed. it happened almost three weeks after a larger earthquake killed nearly 8,000 people. a be drew simmonds has more from
