South Sudan refuses to withdraw troops from oilfield
The President of South Sudan, Salva Kiir, has said he will not withdraw his troops from the Heglig oilfield on its disputed border with Sudan.
Speaking in parliament, Mr Kiir defied calls from the UN and African Union to pull out troops, after days of clashes.
He urged MPs to mobilise their supporters and prepare for war should Khartoum refuse to talk.
Meanwhile, South Sudan's army spokesman told the BBC that Sudanese aircraft had bombed two towns, killing one person.
