State broadcaster ORF said the weapon appeared to be a rifle. Some of those injured are said to be in a serious condition. The mayor of Nenzing, Florian Kasseroler, said the concert was a regular event over the past 10 years and had always been trouble-free. The area was reported to be only dimly lit by a few lights and camp fires at the time of the attack, and frightened concert-goers "fled into the forest in a panic" when the shooting started, he said.

Oldest Olympic champion Sandor Tarics, Berlin veteran, dies at 102

The world's oldest Olympic champion, Sandor Tarics, has died at the age of 102 in San Francisco, the Hungarian Olympic Committee MOB said on its website on Saturday, citing information from the family. Tarics was member of the Hungarian waterpolo team which won in the Berlin Olympics staged by the Nazi government in 1936, pushing Germany into second place. He left Soviet-occupied Hungary to settle in the United States in 1949 and earned fame in his new home country as a designer of earthquake-proof building technologies. At the age of over 100, Tarics still drove his car with California license plate "Gold36"' He swam, worked on solving mathematical problems and monitored sports news in Hungary, he said in a interview to MOB late last year. He attended the 2012 London Olympics as the oldest living champion. When asked in the interview if he would also attend the 2016 Olympics in Rio de Janeiro, he said: "We will see, it is hard to plan things so much forward."

Nepal will need 10,000 megawatt electricity after 25 years: WB study Kathmandu

May 20, 2016- The World Bank (WB) study has revealed that Nepal will be in need for 10,000 megawatts of electricity by 2040. The three-year study held under the title 'The Benefits of Expanding Cross – Border Electricity Cooperation and Trade in South Asia' has shown that electricity demand in domestic consumption for Nepal after 25 years will touch on 10,000 megawatts. WB researchers Michael Toman and Govinda Timilsina carried out the study weighing countries' capacity for generating electricity, inter-nation trade and production demand to meet the goal among the South Asian countries excluding the Maldives. In the report, the researchers have stated that Nepal can generate 52,000 megawatts of electricity. Nepal will have to spend Rs 800 billion to meet the domestic demand for electricity of 10,000 megawatt after 25 years, the research showed. The World Bank has invested a total of around Rs 35 billion in Nepal on various energy projects and in hydro power. It has proposed an ambitious plan for spending Rs 100 billion in addition in electricity generation, development and reformation programmes. Speaking at a programme held to launch the research report, researcher duo Timilsina and Toman shared that the study had indicated that regional trade of electricity did not grow as anticipated due to slow pace of regional cooperation, policy level and technical improvement and lack of institutional system. The study has underlined the need for Nepal – with unbounded possibility of electricity generation – to seek institutional reformation of the Nepal Electricity Authority (NEA), form a separate body for transmission and electricity generation and to adopt multi-buyer model from single buyer model and build trade linkages with Bangladesh among other countries. Nepal must keep at the centre the expansion of market-based power trade linkages with India, expand investment for broader development of hydro power sector and ramp up policy-level and institutional reformation, according to the study.

How much gold is there in London - and where is it?

From the section Magazine The Queen inspects one of the gold vaults in the Bank of England in 2012Image copyrightWPA POOL Image caption The Queen inspects one of the gold vaults in the Bank of England in 2012 The world's biggest bank has agreed to buy a vault for gold and precious metals in London. But how many of these vaults are there, and how much gold do they hold, asks Claire Bates? The streets of London may not be paved with gold, but there is certainly a huge amount stored underneath them. About 6,500 tonnes is stored in seven vault-systems under the city. The largest by far lies in the Bank of England. It holds three-quarters of the gold in London, or 5,134 tonnes. Most of the gold is stored as standard bars weighing 400 troy ounces (12.4 kg or 438.9 ounces) - there are about 500,000 of them, each worth in the region of £350,000. But the official reserves of the UK Treasury account for less than a tenth of this. "Just 310 tonnes of the gold in the Bank of England is from the UK Treasury, the rest is mostly commercial," says Adrian Ash of BullionVault.com. ADVERTISEMENT The gold is held in a system of eight vaults over two floors under Threadneedle Street in the City. This is to spread the weight and prevent the vaults from sinking into the London clay beneath the bank. There are six smaller commercial vaults inside the M25, owned by banks like JP Morgan and HSBC. Three are around Heathrow Airport. The vault bought by ICBC from Barclays is one of these vaults within the M25, but its exact location is secret. It holds 2,000 tonnes, making it one of the largest in Europe. It is reported to have taken a year to build. GoldImage copyrightGETTY IMAGES According to Adrian Ash, a host of private concerns hold gold in London's vaults. "It will be investment funds, hedge funds, wealthy families, trust funds that are backed by gold, that kind of thing," he says. The Bank of England's vault is the second largest in the world behind only that of the New York Federal Reserve, which holds about 6,300 tonnes. "London is interesting as it doesn't produce gold or refine it, nor is there much consumer interest. However, it is the centre of the wholesale gold market. It's the fourth-largest importer of gold and the second largest exporter. When you request a price of gold it is given as 'Loco London' - the price of gold delivery in London, which is the baseline," says Ash. "This is because the UK time zone is between Asia and the US, it has a historic connection to the gold standard and a strong history of property rights, political stability and free trade. It also has good vault facilities." The Barclays vault bought by ICBC is not thought to have been emptied before the sale. "My understanding is that it's being bought as a going concern, they haven't just taken over an empty vault," says Ash. The investors, jewellers, mining companies and others storing their gold in vaults such as these will now pay pay ICBC instead of Barclays for the privilege. More from the Magazine Imagine if you were a super-villain who had taken control of all the world's gold, and had decided to melt it down to make a cube. How long would the sides be? Hundreds of metres, thousands even? Actually, it's unlikely to be anything like that size.
