down with the czar the rallying cry that brought together thousands of russians opposed to president vladimir putin they gathered in city squares across the country voicing their dissent and holding signs denouncing corruption. and i think that every responsible citizen should express their opinion that's my duty as a citizen of the russian federation because i love my country and i want something here to change yet stable i'm fighting for democracy because today's russia is an authoritarian monarchy with an element of totalitarianism and i think we need to fight against that in every possible way so soon with a woman she should for i want to defend my home country because it has been taken over by some sort of engine made monsters who are stealing our money and our freedom. was the was it was opposition leader alexei navalny who had called them on to the streets. and they had been banned from standing for office in the recent presidential elections. i was kiosks

a crowd resists the city that belongs to putin i know they respond. me had just begun his speech when he was grabbed by waiting police arrested for disobedience and organizing an unsanctioned rally. novelli was only one of many people arrested by police in a weekend of unrest that mas the start of putin's fourth term in office. is spoke with our correspondent emily sure went in moscow earlier asking what the atmosphere was like during these protests. the atmosphere i would say was was tense from the beginning even as the demonstrators assembled on pushkin square in the center of moscow there were actually putin supporters waiting for them who basically started a shouting match with them they were shouting for putin and the demonstrators

assembling there were shouting for russia without putin and were shouting against putin and soon after that the arrests started there were groups of riot police out in force basically grabbing people out of the crowd and putting them into police vans now there was some defiance among the protesters as well after the police cleared the square some of them kind of returned to the square and kept assembly around the pushkin monument on the on the center at the center of the square as police kept arresting them as well now police here say that three hundred people were arrested just in moscow observers say the number is more likely to be around six hundred now it's worth noting that the protest here wasn't authorized but protests also took place in several other cities in fact around ninety cities today people came out in support of not me and some of those protests were authorized but there were arrests across the board that was you know you correspondent

emily sure when reporting for us from moscow in slovakia instead of celebrating i'm a wedding friends and family all morning murdered journalist young and his fiance martina. could siac have been investigating high level corruption in the country there are still unresolved murders in february have led to mass protests which triggered the resignation of the prime minister and the demands to battle corruption and protect press freedom. it should have been one of the happiest days of their lives but in place of their wedding friends and family are honoring the murdered journalist ian could see a contest fiance martina with a memorial concert. is where we can accomplish that. investigation of mass murder as well as causes of corruption can be investigated

it's not known who shot could siak and his fiance at close range in late february but when he died the journalist had been working on an article about alleged connections between leading slovak politicians and the italian mafia in the gulf that in the article could siac named people and companies we have checked all the names and connected them to seventy criminal cases we're looking into possible links. prime minister has a bad fit so has resigned but behind the scenes many believe he's still pulling the strings that's prompted tens of thousands of people to protest. slovaks are furious there have been recent nations but not enough. above all corruption must stop we need more public scrutiny. that seems unlikely in light of the latest development the country's public broadcaster

want to urge the baltic states and also the nordic countries to do everything possible to stop this project from going any further. security forces on the russian escort ships letting these environmental activists out of sight for a moment and have tried repeatedly to push the greenpeace ship away. naturally it's uncomfortable for the operator when we say quite clearly that this is not in order that it's dangerous and it's dangerous for the environment and a step in the wrong direction they don't want that in the. bush you know. starting next year the could you make lomonosov would generate seventy megawatts of electricity but russia has no experience with such an atomic power station and it's exactly that which worries greenpeace in the east siberian sea there are icebergs

a powerful alice five rocket is propelling the mars insite lander to the planet's surface as we speak the journey is expected to take six months upon arrival the probe will be set deep under the planet's crossed for clues about how it formed the launch is two years late due to equipment problems the delay also ramped up project cost to more than eight hundred million dollars a solar and battery powered lander is designed to operate for twenty six earth months as scientists have been eager to gather data on the red planet's interior for decades. we know a lot about the surface of mars we know a lot about its atmosphere and even about its so i honestly are but we don't know very much about what goes on a mile below the surface much less two thousand miles below the surface down to the center this heat probe should be able to fill in some of those gaps developed by scientists at the german aerospace center it will measure the temperature of

individual underground layers and determine how efficiently these layers conducts heat to do this the probe will have to burrow deeper into mars surface than any previous drill. another instrument will monitor how much mars north pole wobbles as it orbits the sun. and for the first time a seismometer will measure seismic five gracious on mars surface caused by earthquakes and meteor strikes the data acquired by all three experiments will make it possible to make new suppositions about the inner structure of mars and the information will help scientists to reconstruct the early development of rocky planets such as the earth mars venus and mercury. this will allow them to look back in time to when the super heated elements separated a court. into their densities and formed layers in the young planets. the structure

of the planets consists of a dense metal core less dense mountain and a rocky outer crust formed as the planet cooled. on mars this process appears to have been faster and ended earlier than on earth there even today we can see the traces of this early development phase on the earth these traces have been almost completely obliterated. ex manchester united manager alex ferguson has undergone emergency surgery on a brain haemorrhage ferguson who's seventy six is recovering in hospital and a statement united says the operation went quote very well the scot retired as the club's manager and twenty thirteen after nearly twenty three years in charge ferguson is the most successful manager and british football he's won thirty eight trophies with united including thirteen premier league titles. and watching t w
