shooting. the countries mean gun rights group holds its national convention in the same state of our cur protestors gathered outside the convention hall. make you demanding better gun control laws many, but avoid that. the meeting is even taking place. i think that they should feel safe for being here. days after shooting while some cancelled their appearances. former us president donald trump took the stage to say that the problem was not too many guns, but too few. from this day forward, every school in america should have a police officer or an armed resource officer on duty at all times. as the age old saying goes, the only way to stop a bad guy with a gun is

a good guy with a gun. but even with armed policemen present 21 people were killed in your body. despite the police of families at the scene, police waited for 40 minutes before engaging the shorter officials have now accepted that this was a mistake. that, of course, it was another right to say long as it's very, there's no, no excuse for that. but again, i wasn't there, but i'm just telling you for what we know. we believe there should have been an x ray of that as soon as you can, while many american stand by their constitutional right to bad arms. others wonder how many more tragedies it would take to enforce strict gun control in the u. s. and d, w. correspondence stuff and simon's is in houston, texas, where the n r a convention is taking place. here's his assessment of former president donald trump's speech api event. your no surprises there from the former

president, president trump bird toting the same horn he always did. as did governor about here, the governor of texas sane and blaming mental health issues and mental health problems are a mental health pandemic group of damage in the united states. for, for example, what happened a few days ago and you've all there. but many americans now is especially now after this incident won't change change, meaning not touching the constitutional 2nd amendment, but better restrictions more control. so this or what happened a few days ago is not going to happen anymore or is made much hotter. stephens, i'm reporting there. well, ukraine is warning that its troops may have to pull out of the eastern don bass region to avoid being surrounded by russian forces pro russia separatists say they have taken the strategic railway hub town of lee men. russian forces are also advancing from 3 directions on the nearby twin cities of severe gnats,

and at least he chanced, ukrainian control said he is in the loo. hans gretchen have come under relentless bombardment, seeking safety under ground for those still in several, danielle basements like this are the best hope of escaping the relentless brush and shelling. they tried their best to go on as normal, but the mood here is desperate. i lost my serv. i don't syndrome overs turner's foreman's explosions. and so marshall will i just, warmer i just have to order when most crucial or more hawaii ukraine says 90 percent of the housing in the city has already been damaged by shelling. russia says it's a tillery has been pounding ukrainian military targets as part of its effort to

risk control of the last part of the loo. hon screeching in ukrainian hands. why moscow is also trying to cut off supplies to the ukranian, defend us. striking this warehouse in the east and town of buck mode were a critical supply route to the besieged cities begins. but while russian forces may be making advances, ukraine's determined drifts distance goes on with the ukrainian military release. this footage, it sad shows us try go ne russian position in a village just outside several. don yeske, another sign that for moscow it's offensive is likely coming at a heavy cost. earlier we spoke with samuel bennett, a military expert with the washington based center for naval analysis. here's his assessment of the latest developments in eastern ukraine. i think it's a little too early to make any definitive conclusions about how this particular russian advance is going to go there. so opportunity for counter attacks by the

brain and forces by the rough forces. what is happening right now is probably reflection that the ukrainian forces have in fact, suffered a lot of losses. they've suffered attrition. they're running out of manpower and supplies. russian military has more of the same. they have more soldiers, they've more supplies to have shorter logistics and supply lines. and so we're looking at a situation where russian military is bringing all of its numbers, all of its forces to bear against an exhausted ukrainian defense. but again, we shouldn't probably jump to conclusions whether or not this is going to be a turning point because ukrainian forces can still launch counter attacks. and satellite images have become one of the key sources of information as the war unfolds, photos and videos taken from space, document events on the ground, and can provide vital evidence of atrocities. images like this one, showing the destruction of mary. you pull a,

providing crucial insights into rushes will in ukraine. satellite technology has become a game changing tool in documenting atrocities. this is mary, you pulled the full, the russian invasion there. this is how the city looked afterwards. mary, pulse theater where hundreds of civilians were sheltering before a devastating ass strike. the word children is written on the ground on either side of it as this next image shows that did nothing to deter the attackers. these are just some examples of how satellite imagery often captured by commercial companies is helping investigators pinpoint what's happening on the ground. when russian troops withdrew from the city of boucher, near kiff, ukrainian forces discovered streets lined with the bodies of civilians. russia claimed these scenes were staged by ukraine after its troops had gone. but a satellite image showed what appeared to be bodies lying in the street nearly 2

weeks before the russians left the town. it showed how these pictures can also provide evidence of potential war crimes. year shouldn't think what we have conclusive evidence, model satellite images, and we can conduct a full and transparent investigation. that is what we're interested in a maximum access for journalists, maximum cooperation with international institutions. involvement of the international criminal court, complete truth and full accountability. commercial satellites mean pictures like these, showing what appears to be mass graves and now widely available. it's changing the way war crimes are investigated and could prove vital in ukraine's efforts to hold perpetrators to justice. steven ward is a senior director at max, our technologies, and he told us more about how the satellite company operates in the war. well, we track the news, we work very closely with organizations like yourself. and so we are constantly

keeping track of the latest the, the most significant areas to watch. we are also tasking and looking at areas based on what our customers are asking us to do. so every day we're trying to figure out what areas are most important, what areas have the highest priority? what areas do we need to be able to collect and then refresh monitor to see what's happening. the best resolution we can currently do is 30 centimeters and resolution . that's about think of it is a very small amount of detail or very good amount of detail. we can identify people that we can't detect who they are. we can see that we can see a person, we can see a crowd of people and we can identify the face. we can see that kind of personal behavior and world in a larger perspective, we can see things like the windshield of a car. we can see the 2, but in artillery gun we can see attack or an armored personnel carrier. we can see a grave. and so it's this level of detail and resolution from space that is able

pride, this kind of forensic quality imagery that then can be used for investigations for documentation, etc. so let's bring you up to speed now with some of the other stories making news around the world environment and energy ministers from the group of 7 leading duster all nations. a g 7 have agreed to phase out coal to generate electricity by 2035. the group also promised to double their financial support to developing countries to cope with losses and damage college by global warming. hundreds of students clash with police and the chalet and capital santiago. police use tear gas and water cannons to put out fires and dispersed the crowds after a group through molotov cocktails. the incident took place during and otherwise mostly peaceful protest, demanding more funding for public schools and football now. and the champions league final kicks off later to day in paris is already
