vladimir putin's an auger ration for another term as president. the the the. 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. at my hand 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 the yad 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 to see more of them as you should for i want to defend my home country because it has been taken over by some sort of intimate monsters who are stealing our money and our freedom. 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 there he asks a crowd resist 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. we spoke with our correspondent emily sure when in moscow earlier asking her 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 assembling 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 the servers 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 me and some of those protests were authorized but there were arrests across the board that was correspondent emily sure when reporting for us from moscow in slovakia and set of celebrating i'm a wedding friends and family are mourning murder journalist young and his fiance martinez. had been investigating high level corruption in the country there are still unsolved murders in february have led to mass protests triggered the resignation of the prime minister amid 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 the.

investigation of mass murder as well as causes of corruption can be. it's not known who shot could siac 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 because 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 and nights of the latest development the country's public broadcaster recently fired several journalists they'd signed an open letter against corruption in the media. now some of the other stories making news around the world police in paris have fired tear gas at some protesters during a day of largely peaceful demonstrations across the country tens of thousands of people protested president emanuel mccall's sweeping reforms a year after he took office critics say his economic and social reforms favor the wealthy and corporations by cutting some worker protections. a coal mine explosion has killed at least sixteen laborers and injured several others in southwest pakistan officials say a rescue operation is underway to free about a dozen people who remain trapped inside the mine in baluchistan province according

one hundred forty four metre hull carries two modified naval reactors the fuel rods and on board yet they'll be added in more months. to harden their support we are escorting this ship at the moment to attract attention to it we 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 an order that it's dangerous and it's dangerous for the environment and a step in the wrong direction they don't want that. pushed you know. starting next year the could you make lomo sauf 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 and reefs an accident with the reactor could contaminate large parts of the arctic. it's the two hundredth anniversary of karl marx's birth and a massive statue in his likeness has been unveiled in the german town of tree air where he was born in the town have grappled with the decision to accept the statue which is a gift from china at unveiling has been controversial just like the revolutionary philosopher himself. he's the most famous figure to emerge from the city of true karl marx this five and a half meter bronze statue commemorating his birth is a gift from china and is expected to bring more tourists but so far the newly unveiled statue is attracting critics supporters of the fallen gold movement which

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 gratian 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 according to their densities and formed layers in the young planets. the structure of the planets consists of a dense metal core less dense mantles 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. manchester united manager alex ferguson has undergone emergency surgery on
