There is shock and outrage in Hong Kong after the brutal stabbing of a veteran newspaper editor.
Kevin Lau, a journalist in Hong Kong known for his tough reporting on China, is fighting for his life after a knife attack by an unknown assailant.
Last month, Lau was sacked as the editor of the Ming Pao newspaper, stirring public outcry about press freedom in Hong Kong.
Many of Lau's supporters feared his departure reflected Beijing's efforts to limit press freedom and influence independent media in semi-autonomous Hong Kong.
After the knife attack, Hong Kong Chief Executive C.Y. Leung was quick to condemn the violence.
Meanwhile, journalists are stunned that such an attack would take place in Hong Kong - an international media hub that has supported free reporting across the political spectrum.

Samsung's latest flagship smartphone is out. The reviews are in. And the reaction is...
"What you're seeing here is a Samsung that's very much on cruise control," says Chris Ziegler, deputy managing editor of The Verge.
"It's an evolution of the S4, not a whole new phone. There were some of us who were hoping they would take a little bit of a leap here, go to an aluminum body, maybe a new user interface, but really it's just an evolved S4."
Compared to its predecessor, the S5 has a bigger screen, a better camera and a faster processor.
There's also a fingerprint sensor built into the home button, just like what you find in the iPhone 5s.
But one big change in the Galaxy S5: there's a built-in heart rate sensor. Does that score points for Samsung?
"The fact that they included a heart rate sensor in the GS5 really isn't surprising when you consider fitness is a buzzword in mobile now," Ziegler tells me.
Along with the Galaxy S5, Samsung unveiled three smartwatches at the Mobile World Congress – the Samsung Gear 2, the Gear 2 Neo, and the Gear Fit.
For Ziegler and his fellow editors at the Verge, the slender and form-fitting Gear Fit stole the limelight at the big reveal in Barcelona.
"Of the new smartwatches that they showed yesterday, that would be the winner for sure," says Ziegler.

So Facebook purchases the mobile messaging service WhatsApp for $19 billion in cash and stock.
And the world raises a collective eyebrow.
Yes, the app has over 450 million monthly active users. But is it truly worth it?
According to Silicon Valley insider Om Malik, the answer is yes... if you're Mark Zuckerberg.
Malik tells me, "What seems like an insane amount of money is not insane when you feel a little worried about the long-term prospects of the company."

You might not worry a lot about cybersecurity, but it's an issue that affects everyone online.
Militaries and governments see cyberattacks as serious threats.
Businesses and individuals can be impacted by data theft. In fact, just last month, 20 million South Koreans had their personal data stolen in a colossal breach.
Why is this happening? And how can we protect ourselves?
I recently spoke with P.W. Singer, Director of The Center for 21st Century Security and Intelligence at the Brookings Institution. He's also co-author of the newly released book, "Cybersecurity and Cyberwar: What everyone needs to know."
Singer says one factor behind the wave of recent major data breaches is something he calls the "Cybersecurity Knowledge Gap." It refers to political and business leaders tasked with managing cybersecurity but are themselves not cyber-literate.
"This gap is across the board," says Singer." And it's because we have an attitude that - as one White House official said - this is a domain 'only for the nerds.'"
"But we're all on cyberspace, we all depend on it, so we can't treat it as an issue for the I.T. crowd."
"We teach our kids regular hygiene not just to protect themselves but everyone else they connect with during the day," he says.
"We need the same attitude when it comes to cyber hygiene and our collective responsibility at the global level all the way down to individual citizens and netizens."
It may start with updating your password or upgrading your firewall - just one step forward and away from an age of rising cyber insecurity.
