Hundreds of thousands of people flooded the streets of Hong Kong on Sunday in a show of defiance against a government proposal that would allow people to be extradited to mainland China to face charges.

Organizers of the protest say more than 1 million turned out to the streets, or roughly one in seven Hong Kong residents, but police estimated the crowds were far smaller.

He Qiang should be manning his convenience store, but today he's collecting tiny green berries along the road and shooting them at birds with his slingshot. The 26-year-old is distracting himself from his worries. He spent all his savings — the equivalent of $35,000 — on a store that no longer has any customers.

When it comes to Chinese authorities' eagerness to manage perceptions of the way they treat Muslim citizens in the Xinjiang region, it would be hard to beat a recent musical performance staged for an audience of foreign journalists.

On the fifth day of a government-sponsored media tour last month, at a detention facility in the far-western city of Kashgar, two dozen Uighur detainees belted out the American children's song "If You're Happy and You Know It, Clap Your Hands."

On Thursday morning, Sayyad Milne was washed and wrapped in white cloth. His loved ones buried him on a bluff overlooking Christchurch, New Zealand.

He was killed last Friday while he prayed with his family and friends, one of 50 people shot dead at two mosques that day.

He was 14.

Sayyad's classmates from Cashmere High School say he was good-natured, played goalie for the school soccer team and had dreams of playing internationally.

Ahmed Shalaldeh, with his 2-year-old daughter in a stroller, came to the burial to pay his respects.

Residents of Christchurch, New Zealand, are trying to recover and heal following Friday's attack on two mosques, which claimed the lives of 50 people and left more than 30 others in the hospital.

Police say the shooter — a 28-year-old Australian man who live-streamed the attack on Facebook and who is now in custody — likely acted alone. In the wake of the horrific attack, he left a community in pain.

In the fall of 2017, Chinese state broadcaster CCTV aired a series promoting China's achievements in science and technology. One episode profiled a Chinese scientist who claimed to have invented a gene-sequencing machine that outperformed those in the West.

"Somebody said we shocked the world with our machine," a man in his mid-30s says with a proud smile into the camera. "Yes, they're right! I did that — He Jiankui! That's me who did that!"

It wasn't the last time He Jiankui would shock the world.
