Foreign weapons 'fuelling S Sudan conflict'

Weapons from China, Ukraine and Sudan are fuelling conflict in South Sudan, according to Amnesty International.
It says scores have been killed and injured in indiscriminate attacks on civilian areas by both a rebel group and the South Sudanese army.
The group says a "ready flow of weapons" includes Sudanese weapons, Chinese landmines and Ukrainian tanks.
There has been no official reaction from any of the countries to the allegations.
