At least nine people have been killed in Egypt and more than 350 injured in the past two days of clashes between protesters and security forces in Cairo. Soldiers have cleared Tahrir Square of protesters. And footage showed troops beating demonstrators and burning their tents. Al Jazeera has filmed exclusive video of what appears to be a member of the military shooting into a crowd of fleeing protesters. Al Jazeera's Rawya Rageh reports from Cairo.
This two-part special follows a team of doctors conducting a series of groundbreaking experiments as they climb Everest, the world's highest peak. From their laboratory tents, pitched in -25°C conditions, the experts use their own bodies for medical tests. They push themselves to the limit to better understand the human body's behaviour in a low-oxygen environment. The team hopes their work will lead to new, life-saving treatments for intensive care patients suffering from hypoxia, a shortage of oxygen in the body.
