    YouTube has deleted thousands of videos promoting academic cheating in the last week after a BBC Trending investigation.

    The videos all advertised essay-writing services, which can lead to serious penalties for students.

    Facebook and Google have been asked by a regulator to stop making money from adverts for these companies.

    All the social media companies say they are taking steps to discourage dishonest behaviour.

  6. US exports more oil than it imports for the first time

    Oil field

    New data released on Thursday showed that last week America exported more crude oil than it imported - the first time this has happened, according to the US Energy Department whose figures go back to 1973.

    Adding up all imports and exports of crude, the US exported a net 211,000 barrels per day in the week to 30 November.

    Kyle Cooper, a consultant at ION Energy, asked: "So when does the US send a delegate to OPEC meetings?

    "It's really quite amazing. I do think that will occur more and more often in coming years."

  7. Ottawa had advance notice of Huawei arrest

    Canadian Prime Minister Justin Trudeau

    Canada's Prime Minister Justin Trudeau says that Ottawa had a few days advance notice that the arrest of Huawei's chief financial officer Meng Wanzhou was going to happen.

    Ms Meng is the daughter of Ren Zhengfei, who founded the controversial Chinese telecoms group.

    Ms Meng was arrested in Canada on Saturday. America is seeking extradition of Ms Meng over possible violations of US sanctions against Iran.

    That same weekend, the US and China were meeting at the G20 summit in Argentina to discuss the ongoing trade war between the two countries. They agreed to a 90-day truce.

    Mr Trudeau said: "The appropriate authorities took the decisions in this case without any political involvement or interference."

  8. HSBC monitor reported suspicious Hauwei transactions - report

    Huawei sign

    The Wall Street Journal is reporting that a federally-appointed monitor at HSBC flagged suspicious transactions in the accounts of Huawei Technologies to US prosecutors seeking the extradition of the Chinese telecom equipment maker's chief financial officer who was arrested in Canada on 1 December.

    The monitor, who evaluated HSBC’s anti-money-laundering and sanctions controls, gave information about Huawei transactions to federal prosecutors in the Eastern District of New York, according to the Wall Street Journal.

    The monitor was installed by the Department of Justice as part of a deferred prosecution agreement after HSBC settled claims that lax controls allowed Mexican drug traffickers to launder cash through the bank.

    The Dow Jones Industrial Average has erased some of its earlier falls and is now down 367.26 points, or 1.4%, at 24,659.81.

    Another senior person at consumer goods giant Unilever is retiring.

    This time, it is chief marketing officer Keith Weed who is leaving the Marmite-maker after 35 years.

    He says: "It's with a happy and heavy heart that I've decided to retire from Unilever in April. It's been over a year in planning with exciting challenges to follow."

    Last month, chief executive Paul Polman announced that he would retire and will be replaced by Alan Jope.

    It came less than two months after Mr Polman's plan to change Unilever's structure was scrapped in the wake of shareholder criticism.

We have been working hard on resolving the UK data issue since early this morning. The faulty software that has caused these issues is being decommissioned. Our priority is to restore full data services on the network by tomorrow morning.

  12. One million barrels or bust

    Oil barrels

    OPEC is yet to release any details of a plan to cut oil production, pending a meeting on Friday with the likes of Russia.

    But a reduction of anything less than one million barrels per day (bpd) just isn't going to cut the mustard, according to Bjornar Tonhaugen, head of oil market research at Rystad Energy.

    He says: "We believe a cut announcement that effectively removes anything less than one million bpd of 2019 supply would be interpreted negatively by the market."

  13. O2 and Ericsson to do 'full audit'

    Telefonica UK's chief executive Mark Evans is being careful not to criticise Ericsson which supplies telecoms network equipment to O2, whose customers are suffering a data outage.

    "This is the first problem we've had of this nature with this software," he tells BBC News.

    But he adds: "What we will now do is a full audit, a thorough audit, across both organisations to ensure whatever steps can be taken will be taken to provide the continuous service that our customers expect and deserve."

  14. O2 pledges to 'make it up to customers'

    Asked whether O2 customers who have been affected by today's data outage can expect compensation, Telefonica UK boss Mark Evans, tells BBC News: "Today, I've been speaking to many of out customers and they've expressed their frustration to me, understandably. But they have also said to me the priority is the restoration of the network so our sole focus has been on precisely that.

    "That said, O2 will find a way of making it up to our customers," he says. "But at this stage I don't want anything to detract from the restoration of our network."

  15. Ericsson 'gives assurances' O2 network will be 'fully restored'

    The O2 data failure has been going since 5am on Thursday morning.

    Telefonica UK boss Mark Evans says: "I recognise the impact that we've had on our customers' lives but we have had hundreds of people from [network equipment supplier] Ericsson and O2 working around the clock to identify the issue and resolve the problem.

    "We are confident we know what the issue is. We are starting to restore the network this evening and we are confident - Ericsson has given me assurances - that by tomorrow morning it will be fully restored."

    When that was short-lived.

    Oil prices are heading back down on reports that Saudi Arabia's oil minister Khalid al-Falih said OPEC is not confident of reaching an agreement with Russia to cut output during a meeting with non-OPEC on Friday.

    "No, I am not confident," he said.

    "We're still debating the distribution" of any possible cuts, he said.

    Brent crude is down 3.93% at $59.14 a barrel and West Texas Intermediate is off 3.65% at $50.96.
