brent: i'm brent break off. good to have you with us. we begin with the terrorist within. germany's domestic intelligence agency says it suggests an employee of islamist extremists. national media are reporting that a 51-year-old man has been taken into custody, accused of gathering sensitive information to plan a bomb attack on intelligence headquarters in the western german city of cologne. officials uncovered his activities about a month ago. we want to go to simon young. he is on the story for us in good evening to you, simon. what else do we know about this case? because just broken in the last hour or so. simon: a few details have emerged. the domestic intelligence

agency, officially known as the office for the protection of the constitution, has said that this man has admitted giving away some confidential information that he obtained from within the agency. he gave that to somebody that is in contact -- he is in contact with of the internet, not knowing that that contact was an informer for the domestic intelligence agency. they also say that he was offering yet more information. a newspaper has said that he was planning this bomb attack, as you mentioned, against the headquarters of the agency in cologne, and that he has admitted doing that. some of these details are only just coming out so we should treated with caution. brent: it begs the question, how is it possible for an islamist to embed himself or herself into germany's domestic intelligence service? simon: yes, well, that is a mystery at this stage. according to "der spiegel"

magazine, this man was only recruited in april of this year, and he was not behaving suspiciously or giving rise for any concern during his training. they also report, for instance, that his family was not aware of his conversion to islam. the agency had recruited him to observe islamist extremists in germany. there is a lot of questions there. i think we will just have to wait for more details to come out in the coming days. brent: simon young on the story for us tonight here in berlin. thank you very much. here in germany, authorities are planning hackers for internet outages that have hit hundreds of thousands of users since sunday. last month a similar hack cut off axis -- access to some of the world's best-known websites, including twitter and spotify. now it is deutsche telekom,

germany's biggest internet provider, who says it managed to halt the attack, saying it could have taken the internet out across the world. reporter: nearly one million internet routers were forced off-line in germany. deutsche telekom and german authorities are convinced it was a cyber attack. "we are certain that was deliberate influence from the outside. someone try to affect the routers with malicious software. fortunately, the attempt was successful. the route is crashed and users can go online." could russia be the culprit? the chancellor has no indications in this together case, but in general, germans should consider this new reality. "cyberattacks like this, or russian warfare, is now part of everyday life, and we have to learn now how to cope with them. " germany's federal intelligence agency warns of cyberattacks and

disinformation campaigns originating in russia, particularly ahead of next year's parliamentary elections. -- "there is not a single provider in the world that could of filtered this attack out. this would create a whole new dimension. we are going to see similar attacks happening in the two months. whoever is behind the most recent attack, intelligence agencies and politicians are alarmed. the upcoming 2016 election in germany will be a virtual campaign against disinformation and hackers from cyberspace. brent: brazil has declared three days of national mourning after 75 people died in a plane crash

involving players from the country's chapecoense football team. colombian authorities said the plane chartered aerospace took off from santa cruz in bolivia and went down in a mountainous area shortly before it was supposed to land at medellin international airport. three of the six survivors are chapecoense players. they were on their way to play the biggest game in the soccer club's history. reporter: it was meant to be the trip of their careers, but ended like this. the chapecoense players were heading to the biggest ever game. nearly the whole team died in the crash, as did most of the journalists, officials, and club guests on board. football-mad brazil is stunned. its president declared three days of mourning.

"i want to express my sadness for the awful incident which has caused the death of the soccer team and many people who accompanied to the team. it happened early this morning. it is extremely sad." team fans held vigils to pray for the victims. the club's vice president struggled for words. "everybody has placed their confidence in god that things will go well for us. our chapecoense will have to go on. it is difficult, it is so difficult to speak. i don't have any more opinions. i don't know what else to say." this video is one of the last of the team, checking in for their flight. then full of excitement, ahead of the match of their lives. brent: i'm joined now by a

journalist in são paulo, brazil. good evening to you. do we have any news about what could have possibly caused this crash? >> well, it is becoming clear that this is going to become a very long and possibly bureaucratic investigation. at the very least five countries involved, brazil and colombia, obviously, but also the u.k., where the aircraft was manufactured, and venezuela, and so far, the main theory, the leading theory over the cause of the crash, remains that it was an electrical failure. some officials in the brazilian air force have been analyzing preliminary data, and they are all saying that the information they have is consistent with that kind of scenario, such as the pilot using maneuvers such

as bringing the plane to a very low altitude and various low velocity, as well as doing you turned -- u turns and so on. there are theories, but the authorities are still keeping quiet about a reason. brent: for the football nation brazil, this is something like a national tragedy. however zillions reacting to this news -- how are brazilians reacting to this news? this was a small club that had huge dreams. >> yes, football certainly has an enormous role in brazil's identity as a whole. it has taken a huge emotional toll for all brazilians. there is an overwhelming sense of sadness and morning and shock from the media, that we lost over 20 journalists today, from

all soccer fans, family, everyone. i think the fact that this team was a small team, and under dog, you might add, resonates with the brazilian public even more, because we are facing a deep economic recession, we are facing political turmoil. at this certain time it was the kind of message brazilians were holding to. brent: what do we know, if anything, about those who were able to survive the crash? >> well, what we know so far is that there were five survivors. one of them as a journalist, three of them are players, and one of them is a cap and remember. they are all -- cabin crew member. they are all in stable condition. one of the players is undergoing surgery, and are reports in the press that he might not, for

instance, be able to play again. but this is all very preliminary. there is also another player whose status is not yet confirmed. there is a lot of apprehension all of the country, and his family, to whether what happened with him. he was recovered from the site alive. and there were reports earlier today that he has passed away, but then again, red cross a little bit after has said that he was alive, only transferred to a different hospital. and yet no word on his status. we are waiting. brent: yeah, a lot of questions and a lot of sadness tonight. >> thank you. brent: 30 years ago, the chernobyl disaster released a radioactive cloud over large parts of europe, forcing hundreds of thousands of people

to abandon their homes. back then, soviet authorities rushed to encase the reactor with a concrete sarcophagus. but that has reached the end of its life span. now the ruins of the nuclear power plant has been secured for a second time by a massive still down. -- steel dome. reporter: i see an overcast day at the crippled chernobyl nuclear site, but inside the heated tent, there is a celebratory mood. among the top officials attending the in actual it, ukrainian president petro poroshenko. he had high praise for what he called an historic construction, comparing the new encasement to the eiffel tower and the statue of liberty. "today the consortium guarantees 100 years of nuclear safety. a lot of people had doubts. a lot of them didn't believe in this. congratulations. yes, we did it."

it took almost a decade to build the cover, and 36,000 tons of steel. technicians at firms from all over europe helps complete the 2 billion-euro project. the steel encasement forms in cover over the ill-fated reactor number four, the site of europe's first nuclear disaster 30 years ago. on the 26th of april, 1986, there was an explosion at chernobyl's reactor number four. a radioactive cloud spread over large parts of the then-soviet union, reaching as far as western europe. a provisional and casing was hastily built to contain the radiation. but it soon became unstable and threatened to cave in. many areas of the countryside are still considered radioactive. >> moving together, 2 halves, sliding the titanic shelter into position over this reactor, is

like closing the wound, a nuclear wound that belongs to all of us. reporter: the old in casing has yet to be dismantled, but it is not known who will pay for it. what is clear to the ukrainian government are its plans for renewing the site. it wants to make it into a center for the production of renewable energies. brent: well, if you thought you knew everything about the world's fastest man, think again. a new documentary about usain bolt has hit the theaters. it is called "i am bolt." the ninth time all the big champion was on the film's premiere. it gives an inside look at his intensive training regime. you'll also hear from those close to bolt about the sprinters personality. it is a fast one, i hear. usain bolt has to decide whether he will continue blazing for the track.

faster decision there. you are watching "dw news." still to come, the so-called islamic state has claimed responsibility for the monday car and i for attack at a university -- and knife attack at a university in the u.s. state of ohio. we will be back after a short break.

i brent: welcome back to "dw news ." brazil has declared three days of national mourning after a plane carrying football players from the brazilian club of chapecoense crashed, killing 75 people. the so-called islamic state has claimed responsibility for the attack that took place monday at a university in the u.s. state of ohio. 11 people were injured when a man drove a car into a crowd and then started stabbing people. police officer shot and killed the man, who was later

identified as a somali-born student. let's pull in our washington correspondent richard walker on the story for us. good evening to you, richard. how seriously are authorities taking this claim? richard: well, the claim was posted on a news organization which is seen as the islamic state's effective news agency for the so-called islamic state. and this is the place where the group has typically posted its claims of responsibility, particularly for attacks taking place not necessarily in iraq and syria, but outside in other parts of the world over the last year or two. so with that in mind, it will be taken very seriously by intelligence services and of course, investigators who are looking at what happened in columbus. brent: is there any concrete evidence that the suspect was a supporter of i.s.?

richard: well, even before this claim came out, we where hearing from authorities right up to the level of the white house that possible extremist motivations behind this attack were being looked at by investigators. so far the investigators themselves are being tightlipped, as you would expect, just a day after what happened. but off the record, some have been speaking to american media and indicating they are looking particularly at facebook posts which might add to that degree of suspicion. we really have to caution, is very early days and we won't be able to take our look at this kind of evence until it is presented openly pit at this point it is beginning to look like this could potentially be one of these so-called lone wolf attacks, or you have an individual working alone, it becomes radicalized by material they find on the

internet, and goes on to cause this kind of violence. by its own very definition, these kinds of attacks are particularly difficult to prevent. brent: all right, our correspondent in washington, richard walker. as always, thank you very much. russia's foreign minister says there has been no breakthrough in tuesday's talks aimed at ending the fighting in eastern ukraine. sergei lavrov was speaking after four-way talks with german, french, and ukrainian counterparts in the belarusian capital, minsk. he said there had been no agreement on a roadmap to peace. germany's foreign minister described the negotiations as difficult, saying that a political agreement still a long way off. although conflict has become less intense since last year's agreement, there are still daily skirmishes. our reporter reports from the ukrainian front line. reporter: this road leads right into the water.

the intersection is scarred by the heavy fighting it has witnessed. omission regularly sends observers to note any breaches of the minsk agreement. this morning things are relatively quiet. ukrainian soldiers take us to the front line. this unit has been stationed in a forest for six weeks now. the commanders as he is glad they haven't lost any men, yet. just across from them, no man's land. this so-called gray zone is a demilitarized area. but despite its name, shots continue to be fired at ukrainian soldiers. the sound of gunfire echoes across the frozen fields. the platoon leader calls this "front music." he says the separatists aren't observing the cease-fire. "the other side is trying to provoke us so that we opened firet them. but we stay still and they shoot ."

the osce says the ukrainians have also been breaking the cease-fire, but the military denies this. "only when the light or well-being of our soldiers is in danger, that is when we give the orders to fire. but if this is the case, we only use weapons allowed by the minsk agreement." on this day, the ukrainian military has already counted 37 violations of the cease-fire. the independent osce report is not yet available. >> four eastern ukraine, this is the third winter at war. our efforts to revitalize the so-called minsk peace process ended in a deadlock could ukraine and russia-backed separatists cannot agree on a role to bring peace to the region. brent: all right, time for a check of the business news. the oil industry is hoping for a deal that probably will never

come. reporter: that's right. all eyes on the oil-producing countries. oil prices dropped as much as 4% ahead of the opec meeting on wednesday. the aim is to cut production to bolster prices. experience shows that that is easier said than done. many doubt we will see a deal. it means losing market share. in the meantime, the economies of many opec members are suffering. the situation is particularly difficult in iraq. reporter: iraqi troops advancing on mosul. the battle for the city has been raging for a month now with no end in sight. the fighting has cost many lives and plenty of money. retreating i.s. fighters leave burning oil fields behind. iraq's budget is in tatters. the countries dependent on credit for the international monetary fund. in order to keep oil prices high and boost revenue, iraq has announced its willingness along with other countries to scale down oil production ahead of the opec meeting.

>> i think iraq would stick to this because the current level of oil prices is inadequate. it is not sustainable, for us, for other countries. we are prepared to take her own share, our own oil production. they should commit themselves as well. reporter: at the end of september, opec members agreed to cut daily oil production by 800,000 barrels to 33 million barrels. if the agreement is approved on wednesday, the impact is likely to be moderate. 800,000 barrels equals just 2.5% of total output. back in 1983 and in 2008, opec had to slash production by 12% in order to stabilize oil prices. so the proposed cut a not be enough to raise prices and plug the holes in iraq's budget. >> lufthansa is annoying its

passengers once again. the german carrier canceled hundreds of flights today and will ground even more planes tomorrow. pilots have walked off the job over pay for the 15th time. the number of passengers affected by strikes over the past week is now more than half a million come with the lucrative christmas season just around the corner. the union argues that the pilots have not had a salary increase in five years, but lufthansa keeps booking billions in profits. the airline says it has to cut costs to stand up to aggressive competitors. analysts warned that the industrial action could jeopardize the profit target for this year. germany is introducing more flexible labor regulations, or at least it is giving them a try. the government wants to see whether easing working conditions helps comedies and their employees. the pilot project is already controversial. reporter: they don't need to take breaks or sick days. these robots are ready to work day in and day out. working world is increasingly digital.

germany's labor minister acknowledges it is a huge upheaval for the labor market. but he is confident humans will still be needed in the future. "there will be significant shifts in different sectors and professions in the coming years, but the work will not disappear ." above all, the german labor minister is calling for more flexible working hours. she wants to french employers and trade unions a two-year test phase two try this out. during this time, working hours will be relaxed, and employees should begin in the right to work more or less, depending on your personal circumstances. she also proposes that every citizen should be assigned a worker count at the start of their career, with an initial credit. "this would allow them to bridge any income gaps during qualification, when founding a startup, or part-time work or unemployment." but not all the experts on the

panel agreed. the president of the federation of german employers says the labor minister's plans are too costly. >> to the u.s. now, where the economy is growing at its fastest pace in two years. the commerce department unexpectdly rose the third-quarter figure two 3.2% growth. the strong jump is due to increased spending by consumers, who are investing more in housing, boosting building projects. the numbers come at a good time for the federal reserve, which is planning an interest rate hike for next month. and of course we are following that for you right here on dw. back to you, brent. brent: here is a reminder of the top story we are following. brazil has declared three days of national mourning after a plane carrying football players from the brazilian club chapecoense crashed in colombia. 75 people were killed. after a short break, i will be back to take you through the day. we're going to look more at that cyberattack here in germany.

stick around. we'll be right back. [captioning performed by the national captioning institute, which is responsible for its caption content and accuracy. visit ncicap.org]
