The National Alliance leader Lam Akol Ajawin says Juba government stopped them from travelling to Addis Ababa, Ethiopia for the IGAD-Plus peace talks to end South Sudan conflict.
Dr Akol told journalists on Wednesday that a Police Major informed National Alliance delegates that the presidency directed that they should not travel to Addis Ababa without permission.
He says they will continue advocating for their rights in search for lasting peace in the country.
The National Alliance leader says he has no idea whether political parties in the government are permitted to go or not.
