Russian ambassador to Turkey Andrei Karlov shot dead in Ankara

A Turkish policeman has shot dead Russia's ambassador to Turkey, Andrei Karlov, apparently in protest at Russia's involvement in Aleppo.

The killer has been identified as Mevlut Mert Aydintas, 22, a member of the Ankara riot police. It was not clear if he had links to any group.

The incident happened a day after protests in Turkey over Russian support for Syrian President Bashar al-Assad.

Turkey's President said the attack was aimed at hurting ties with Russia.

Recep Tayyip Erdogan spoke to Russian President Vladimir Putin by phone and, in a video message, said that they both agreed it was an act of "provocation".

He said that those who wanted to harm relations between the two countries "would not achieve it".

In televised remarks, Mr Putin said the act was "undoubtedly a provocation aimed at disrupting the normalisation" of bilateral ties and the "peace process in Syria".

While there were protests in recent days about the situation in Aleppo, on a political level the Turkish and Russian governments have been co-operating in the ceasefire operation, the BBC's Turkey correspondent, Mark Lowen, reports.

Before the attack happened, a meeting of the Russian, Turkish and Iranian foreign ministers had been planned in Moscow for Tuesday.

Shocking features Added To Samsung S8

Samsung is to launch its new flagship Galaxy S8 in the second quarter of 2017 where we are expecting to have a bezel-less display similar to Xiaomi Mi MIX

According to Bloomberg, the new Samsung Galaxy S8 will absolutely have no-bezel, and Samsung is going to drop its legendary physical home-button and will replace it by a capacities button infused with fingerprint sensor similar to Apple iPhone 7.

There are rumors around that Galaxy S8 is going to be launch a month later to its due date and it is believed that Samsung is taking increased measures for the success launch after the fiasco of Galaxy Note 7.

The phone will have two different model a 5.1-inch and 5.7-inch similar to the S7. The phone will be powered by Qualcomm Snapdragon 835 and Samsung’s own Exynos SoC.

There are also rumors that the phone will have 6GB of RAM, which seems quite true after various smartphones release with 6GB RAM like OnePlus 3, OnePlus 3T, Xiaomi Mi 5s Plus, Xiaomi Mi MIX and many more.

S8 launch is indispensable for Samsung to raise out of the ashes of Galaxy Note 7 and it will take any possible action to make the launch successful and even after.

The rivalry stands still between the two competitors Apple and Samsung to outnumber each other in the sales of units.

Train drivers at home, Worst Rail disruption

LONDON:  British commuters faced the worst travel chaos on Tuesday as train drivers went on a strike which is considered to be the worst rail disruption that Britain has never seen  in decades.

Southern Rail, which operates trains between England’s south coast and London, informed of severe disruption and cancelled all of its 2,284 services after workers launched three days of industrial action.

According to reports around 1,000 drivers are on strike, which will affect almost 300,000 passengers in the people who travel to London’s Gatwich Airport.

The drivers began a 48-hour walkout on Monday and planned a further 24-hour walkout for Friday and six days on action in January, which has not been decided yet.

The strike is about “driver-only operated trains” which means there would be no guard to assist and open and close the doors of the train for the passengers.

A point raised by the Union leaders about the safety and possible job losses, though the company affirmed that the number of staff will not be affect.

Passengers on routes from Brighton and other key commuter towns in southern England have been experiencing months of disruption to the services and series of walkouts that began in the April.

Govia Thameslink Railway’s owner started the latest strike after he lost a legal bid to halt the action.

Britain’s railways have once experienced this he level of shutdown in 1994 when signal workers went on a strike.

Southern Rail released a consolatory words, said it was “sincerely sorry” that trains were at a standstill.

“These strikes are wholly unjustified and we must find a way forward,” a company spokesman said, adding that it had invited union representatives to talks aimed at resolving the issue.

Mick Whelan the general secretary of the train drivers’ union Aslef, said the union was prepared to negotiate but “it’s up to the company, and the government, to be flexible and end the misery of commuters.”

Chris Grayling, Britain’s transport minister called it a “completely futile, pointless strike”.

Further he told BBC’s Radio 4 that he did not agree with the action but: “I don’t have the power to order people back to work. This is a lawful strike.”

The rail walkout comes after Post Office workers also voted Monday to strike in a row over job cuts, closures and pensions.

Next week, the five days of strike is being carried by the Communication Workers Union which will affect the courier services and shipping of goods while the busiest period, Christmas, is just around the corner.

Earned £90,000 from a Hair cut

LONDON: A British man who suffered a stroke because an artery was damaged during a routine haircut has reportedly received £90,000 in compensation from the salon.

Dave Tyler, a 45-year-old father of two, collapsed two days later during a business meeting, prompting a trip to hospital where a consultant asked him: “Have you had your hair cut recently?”Tyler had his hair washed and cut at the Headmasters salon in his hometown of Brighton, southern England, according to reports in The Times and Mail on Sunday.

Doctors believe an artery was injured when Tyler’s head was bent backwards over the basin to wash his hair, causing a blood clot that led to the debilitating stroke.

He reportedly spent three months in the hospital and was left only able to walk with a stick and unable to drive because of blurred vision.The salon agreed to pay £90,000 ($114,000, 107,000 euros) after Tyler’s lawyers had claimed it had failed to protect his head during the visit in 2011 adequately.The salon referred AFP’s questions about the case to the headquarters of Headmasters, a chain, but no one was immediately available for comment.

According to The Times, similar incidents have been previously recorded in medical journals, and the newspaper cited two other cases of so-called “beauty parlour syndrome”.In January 2014, mother-of-two Elizabeth Smith reportedly had a stroke after visiting a salon in San Diego, in the United States. And in 2000, Pamela Crabb, from Poole, in southern England, also suffered a stroke believed to have been caused by a salon visit.
