That's the message from the United Nations' human rights chief to the Iranian government.

Volker Turk said thousands of people have been killed during the crackdown on anti-government protests, including children and bystanders.

If you follow rock climbing at all, you'll have heard of Alex Honnold.

His speciality is the frankly terrifying art of free soloing.

It's climbing rock faces alone, without ropes, harnesses or protective equipment.

When he became the first person to free solo the 900 metre face of El Capitan in California in 2017, the New York Times called it one of the greatest athletic feats of any kind ever.
