UNITED NATIONS - The UN Security Council demanded on Tuesday that Sudan immediately stop airstrikes on South Sudan and will consider in the coming days what further steps to take to stop clashes between the east African neighbors spiraling into war.
Senior UN officials told the 15-nation body that aerial bombing of South Sudan's Unity State on Monday night had killed 16 civilians, injured several dozen and caused significant damage to infrastructure.
The Sudanese army has denied carrying out air strikes.
South Sudanese President Salva Kiir said the latest hostilities amounted to a declaration of a war by his northern neighbor.
Clashes along the ill-defined border between the former civil-war foes has led to a standoff over the Heglig oil field after it was seized earlier this month by troops from South Sudan, which declared independence last year.
