Kangaroos attacking carrot-bearing tourists spark warnings Image copyright Getty Images Image caption Think twice before hugging for a selfie People have been warned not to feed kangaroos at a tourist spot in Australia following a string of attacks by the animals.
Each week thousands of people visit the grounds of a hospital in Morisset, New South Wales, to see the wild kangaroos.
But some tourists have been kicked, scratched, and left with serious cuts by the marsupials hoping for food - their favourite snack being carrots.
Local MP Greg Piper says urgent action is needed to educate tourists.
"While kangaroos are cute, they are also capable of inflicting injury," Mr Piper told the BBC.
He says the problem has escalated over the past few years following a jump in the number of visitors.
"Social media has changed everything," Mr Piper says.
Instagram, Facebook and blogs have been posting advice on where to get the perfect "Roo selfie" travel fast.

S Korean cleaner may become rich after finding gold in bin Image copyright GSO Images Image caption South Korea's Lost Articles Law means that one cleaner may become rich A South Korean cleaner may be set to inherit a fortune in gold after an unexpected find in a rubbish bin, it's reported.
According to The Korea Times, a cleaner found seven gold bars worth a total 350 million won (£240,000; $330,000) whilst emptying a rubbish bin at Incheon International Airport on 26 April.
The bars, each weighing 1kg (2.2 lbs), were wrapped in newspapers, and police suspect that their original owner threw them away in a hurry because he risked being caught.
Currently, there is no proof that the gold is connected to criminal activity. If none is found, the cleaner, who has not been named by the media, will be able to make a substantial claim on the goods.
South Korea operates a "Finders Keepers" law on goods that are recovered when there is no known owner.

South Korea says US troops will stay despite possible peace treaty Image copyright AFP Image caption Tens of thousands of US military personnel are based in South Korea South Korea's government has said US troops will remain in the country, even if a deal is reached to formally end the Korean War.
There are about 29,000 US military personnel based in South Korea, under a post-war security agreement.
North Korea has previously made giving up its nuclear weapons conditional on the troops leaving the peninsula.
But a South Korean government spokesman said their presence was "nothing to do with signing peace treaties".
"US troops stationed in South Korea are an issue regarding the alliance between South Korea and the United States," said Kim Eui-kyeom, speaking for President Moon Jae-in.
In their breakthrough meeting last Friday, Mr Moon and North Korea's Kim Jong-un agreed to work towards a denuclearised Korean peninsula and a peace treaty to formally end the Korean War.
Cardinal Pell likely to face two trials, court hears Image copyright Getty Images Image caption Cardinal George Pell has pleaded not guilty to the charges Cardinal George Pell is expected to face two trials on sexual assault charges, an Australian court has heard.
The Vatican treasurer 76, has pleaded not guilty to all charges, and has strenuously denied any wrongdoing.
On Tuesday, a magistrate ordered him to stand trial. The allegations relate to the 1970s and 1990s, a court heard.
Cardinal Pell appeared at the County Court of Victoria on Wednesday, where prosecution and defence teams asked for the case to be split across two trials.
If a judge agrees, separate juries would hear allegations against Cardinal Pell about his time as a priest in Ballarat in the 1970s, and charges relating to when he was archbishop of Melbourne in the 1990s.
Much of the evidence given at a previous hearing was not open to the public, and remains confidential.
Cardinal Pell is Australia's most senior ..
Facial recognition to be used at Singapore airport Image copyright Reuters Image caption The trial means there are fewer visible airport staff Singapore's Changi airport is testing a facial recognition system it hopes will speed passengers through the facility.
It is expanding existing uses of the smart ID system and is looking into ways it can replace passport checks.
Reuters reports however, that proposals to use cameras mounted on lamp posts that scan faces to ID passengers has raised privacy concerns.
Airport officials have dismissed "big brother" worries.
Last callOne potentially welcome use of facial recognition could be to spot passengers who have missed the last boarding call for their flight.
"We have lots of reports of lost passengers, so one possible use we can think of is, we need to detect and find people who are on the flight. Of course, with permission from the airlines," Steve Lee, Changi Airport Group's chief information officer, told Reuters.

Afghanistan attack: Remembering BBC's talented Ahmad Shah Ahmad Shah, who has been killed aged 29, was a very unassuming man - but his work as a BBC reporter in Afghanistan was far from modest.
He will be remembered as a versatile and energetic reporter with a wide range of interests and always full of ideas for new stories.
His sense of journalism was sharpening and improving every day.
We found him quiet, modest and clever - someone who was well-informed, always willing to accept a challenge and keen to go the extra mile.
Ahmad joined the BBC from local radio in early 2017 with a brief to cover his home province of Khost, in south-eastern Afghanistan, but he branched out to cover the neighbouring provinces of Paktia and Paktika as well for television, radio and online.
He first started working for the BBC as a freelance contributor before being recruited as a full time reporter by BBC Pashto last year.
For Ahmad, who graduated with a BA in journalism from Khost's Shaikh ..
Taj Mahal colour change worries India Supreme Court Image copyright Getty Images Image caption Students help clean up the Yamuna River, a source of pollution said to be damaging the Taj Mahal India's Supreme Court has instructed the government to seek foreign help to fix what it described as a worrying change in colour at the Taj Mahal.
"Even if you have the expertise, you are not utilising it. Or perhaps you don't care," court justices said.
The court said the famous palace, built in the 17th Century from white marble and other materials, had turned yellow and was now turning brown and green.
Pollution, construction and insect poo are said to be among the causes.
Justices Madan Lokur and Deepak Gupta examined photographs of the palace submitted by environmentalists and ordered the government to seek expertise from inside India and abroad.
The government has previously shuttered thousands of factories near the Taj Mahal, but activists say it is still losing its lustre.
