More than 500 Togolese nationals have sought refuge in neighbouring Ghana because of a government crackdown on opposition protests, the UN refugee agency said Friday. "So far, 513 asylum seekers have been registered by the Ghanaian authorities," UNHCR spokesman Babar Baloch said in a statement. They crossed the border to Chereponi, Zabzugu and Bunkpurugu-Yunyuo in Ghana's remote northwest and most were staying with local families or in community centres, he added. "Togolese seeking safety, including women and children, told UNHCR staff they had fled on foot, walking from their homes in Togo's Mango region, bordering Ghana," he said.
