South Sudan border town Bentiu bombed

Several bombs have been dropped on the South Sudanese border town of Bentiu, amid fears of all-out war with Sudan.

International journalists saw at least two bombs land and a huge plume of smoke rising from a market, where they saw the body of a young boy.
A top South Sudanese military official described the bombing as a "serious escalation" and a "provocation".
It follows weeks of clashes along the border between South Sudan and its northern neighbour.
There was no immediate comment from Sudan's military, but it has always denied carrying out aerial bombardments on South Sudan in the past.
On Sunday, both countries confirmed there was ground fighting in the disputed border region.
Those clashes took place south of Heglig, the oil field which has been at the centre of the recent crisis.
Nearly two weeks ago South Sudanese troops seized control, inflicting a serious military and economic blow to Sudan.
On Friday, the South said it was withdrawing its soldiers following intense international pressure, although Sudan said it had forced them out.
Access to the disputed border region around Heglig is limited, making it difficult to verify what is happening in the area.
The BBC's James Copnall, who is in Bentiu, says it had been hoped that the withdrawal from Heglig would reduce tension but the latest fighting, and aerial bombardments, make it clear this has not happened.
The air raid's main target seems to have been the bridge which provides access to the nearby border region, he says.
The local state governor told the BBC that, as well as the death of the young boy, three people had been critically wounded when a bomb fell on the market.
Our correspondent says South Sudan is building up its troops near the border, and is assuming that Sudan is doing the same.
US President Barack Obama last week called on both sides to defuse the situation.
South Sudan seceded last July as part of a peace deal following two decades of war, which left some 1.5 million people dead.
