The drought in northern Kenya is increasing conflict between the area's nomadic groups, as they travel further to find scarce pasture, according to a development organization. "It's not just the food crisis that is claiming lives," said Oxfam Kenya head Gezahegn Kebede, warning of further deadly clashes unless more aid arrives. The nomadic groups of northern Kenya, southern Ethiopia, parts of Sudan and Somalia have a history of fighting over livestock and pasture but Oxfam says the drought is increasing tensions.
