Concerns over security in some parts of rural Liberia and the battered state of the country's infrastructure will limit the number of refugees able to return home from neighbouring West African countries later this year, the UN refugee agency UNHCR has warned. "We do not want a situation where more (refugees) than we planned return because most of them would end up in internally displaced camps since the facilities are not adequate to receive large numbers of people," Golam Abbas, the deputy head of UNHCR in Liberia told IRIN.
