Protests in Chicago escalated on Saturday night, becoming a tense clash between demonstrators and police over the fatal shooting of a man on the city's South Side.

On Sunday, police released a 30-second video clip from an officer's body-worn camera showing a black man shot by Chicago police had a gun in a holster at his hip. According to The Associated Press, the man was "running away and reaching toward his waist when he was shot multiple times."

Novak Djokovic won the Wimbledon men's singles title for the fourth time on Sunday, defeating South African's Kevin Anderson.

It wasn't a short championship for either competitor – on Friday in the semi-finals Kevin Anderson and John Isner played a remarkable six and a half hour match. That marathon match, in turn, forced Djokovic to play Rafael Nadal over the course of two days, and delayed the women's finals.

The photographs are stunning: a giant mountain of ice towers over a tiny village, with colorful homes reminiscent of little doll houses against the stark, blue-gray landscape.

But for the people living in those houses, that beauty could be life-threatening.

"It's kind of like, if you lived in the suburbs, and you woke up one morning and looked out, and there was a skyscraper next to your house," says David Holland, an oceanographer at New York University who does research in Greenland during the summer months. "I'd be the first to get out of there."
