AP PHOTOS: 'If they die, we all die': Drought kills in Kenya

NAIROBI, Kenya -- The withered carcasses of livestock are reminders that drought has descended yet again in northern Kenya, the latest in a series of climate shocks rippling through the Horn of Africa.

As world leaders address a global climate summit in Glasgow, pastoralists watch their beloved animals suffer from lack of water and food. Yusuf Abdullahi says he has lost 40 goats.

“If they die, we all die,” he says.

Kenya’s government has declared a national disaster in 10 of its 47 counties. The United Nations says more than 2 million people are severely food insecure. And with people trekking farther in search of food and water, observers warn that tensions among communities could sharpen.
