Q: By Chris BaraniukTechnology reporter This year, electricity use at Bitcoin mining data centres is likely to exceed that of all Iceland's homes, according to Johann Snorri Sigurbergsson. He said many potential customers were keen to get in on the act. "If all these projects are realised, we won't have enough energy for it," he told the BBC. Mr Sigurbergsson's calculations were first reported by the Associated Press. Iceland has a small population, of around 340,000 people. But in recent years it has seen a marked increase in the number of new data centres, often built by firms wishing to tout green credentials. Nearly 100% of energy in Iceland comes from renewable sources. Bitcoin mining refers to the work done by computers connected to the global Bitcoin network. These computers solve complex mathematical problems - a process that in turn validates transactions between users of the crypto-currency. The computers that do this validation work receive small Bitcoin rewards for their trouble, making it a lucrative exercise, especially when done at a large scale. 'Exponential growth' "What we're seeing now is... you can almost call it exponential growth, I think, in the [energy] consumption of data centres," said Mr Sigurbergsson. He added that he expects Bitcoin mining operations will use around 840 gigawatt hours of electricity to supply data centre computers and cooling systems, for example. He estimated that the county's homes, in contrast, use around 700 gigawatt hours every year. "I don't see it stopping quite yet," added Mr Sigurbergsson, referring to data centre projects. "I'm getting a lot of calls, visits from potential investors or companies wanting to build data centres in Iceland." He also said that there are so many proposed data centres that it wouldn't be possible to supply all of them. He added that his firm was mostly interested in dealing with companies that were willing to commit to long-term contracts of a few years or more. If Iceland took on all of the proposed Bitcoin mining ventures, there simply wouldn't be enough electricity to supply them all, he added. The crypto-currency mining industry in Iceland was recently given a boost thanks to the launch of The Moonlite Project - a large data centre where various crypto-currencies, including Bitcoin, will be mined. It is set to open later this year and will have an initial capacity of 15 megawatts, though this is expected to increase in the future. Some have questioned how beneficial the rise of the crypto-currency mining will be to Iceland. Smari McCarthy, a member of the Icelandic parliament for the Pirate Party, tweeted: "Cryptocurrency mining requires almost no staff, very little in capital investments, and mostly leaves no taxes either. "The value to Iceland... is virtually zero." He also clarified previous reports that quoted him as saying he was keen to tax Bitcoin mining firms. It has previously been reported that the electricity demand of the world's total combined Bitcoin mining operations may now exceed the energy use of the Republic of Ireland, though this calculation may not be entirely accurate. But as crypto-currencies rise in popularity, mining operations certainly continue to use more and more resources - recent analysis of European energy use in 2017 by campaign group Sandbag noted that Bitcoin mining was contributing to additional power demand in the technology sector.

A: Iceland is facing an "exponential" rise in Bitcoin mining that is gobbling up power resources, a spokesman for Icelandic energy firm HS Orka has said.

Q: There were systemic failures at the state department, but no individual official ignored their duties, it adds. US Secretary of State Hillary Clinton has accepted all 29 recommendations contained in the report. The 11 September attack saw Ambassador Christopher Stevens, as well as three other US officials, killed. The ambassador died of smoke inhalation when he was trapped alone in the burning consulate building, after armed men had stormed the compound. The assault triggered a major political row over who knew what and when. As a result, an independent panel - the Accountability Review Board- was charged with investigating the incident. The report identified the state department's Bureau of Diplomatic Security and Bureau of Near East Affairs for criticism over their apparent lack of cooperation and ensuing confusion with regards to protection. "Systematic failures and leadership and management deficiencies at senior levels within two bureaus of the State Department resulted in a Special Mission security posture that was inadequate for Benghazi and grossly inadequate to deal with the attack that took place," the panel concluded. However, the review has not suggested disciplinary action be taken against any individuals. 'Profoundly lacking' Despite "a lack of transparency, responsiveness, and leadership" among certain senior state department officials, the report found no "reasonable cause" that any specific individuals had "engaged in misconduct or wilfully ignored" their responsibilities. It also said there had been "no immediate, specific" intelligence about the 11 September attack or threats to the consulate. In a letter to congressional committees, Mrs Clinton said she had ordered the state department to implement the investigation's findings "quickly and completely". She outlined some steps the agency would take, including sending hundreds of Marine guards to US missions abroad and assigning a state department official to oversee "high threat posts". In addition, Mrs Clinton said the state department would request more funding from Congress to make improvements to security. The probe concluded that the US personnel had "performed with courage and readiness to risk their lives to protect their colleagues in a near-impossible situation". But the Benghazi mission had nevertheless been hampered by a lack of resources. The reliance on armed "but poorly skilled" local militiamen and contract guards was "misplaced," the report said. "The solution requires a more serious and sustained commitment from Congress to support State Department needs which constitute a small percentage of the full national budget and that spent for national security," according to the review. The probe also criticised the Libyan government's response to the attack, characterising it as "profoundly lacking". The Obama administration's handling of the attack in Benghazi has become the focus of Republican criticism. Officials initially said the attack had developed out of protests against an anti-Muslim video. But later intelligence reports suggested it was possibly tied to al-Qaeda affiliates.

A: Security at the US consulate in the Libyan city of Benghazi was "grossly inadequate" when an attack killed the US ambassador, an official report says.

Q: The Boeing 747 operated by ACT Airlines crashed as it was about to land in fog at Manas airport, 25km (15 miles) north of the capital, Bishkek. At least 15 buildings were destroyed in the village outside the airport, with a number of children among the dead. Flight TK6491 was to have stopped at Manas en route to Istanbul in Turkey. Kyrgyz authorities have declared a day of mourning for Tuesday. ACT is an Istanbul-based airline operating under the name MyCargo. The plane is believed to have been about 14 years old. Deputy PM Muhammetkaly Abulgaziev said on state TV: "According to preliminary information, the plane crashed due to a pilot error." 'Like an earthquake' One witness, Baktygul Kurbatova, told local media: "I woke up because of a bright red light outside. I couldn't understand what was happening. "It turns out the ceiling and the walls were crashing in on us. I was so scared but I managed to cover my son's face with my hands so that debris would not fall on him." Another resident, named only as Tajikan, said she heard "a roar and (what felt) like an earthquake". "Many people were sleeping, everything around was burning. One of the parts of the aircraft fell on our neighbour's house. She and her whole family died." At least 15 people, including six children, were injured, the health ministry said. ACT said the plane had no record of technical faults and had not encountered problems during its flight. One of its two flight recorders has been recovered, the Kyrgyz prime minister's office said. Turkish President Recep Tayyip Erdogan called his Kyrgyz counterpart, Almazbek Atambayev, on Monday to express his sadness at the loss of life.

A:
A Turkish cargo plane flying from Hong Kong has crashed into a village in Kyrgyzstan, killing all four crew and at least 33 people on the ground.
