Nairobi: A US satellite monitoring group says that Sudan`s military is upgrading air bases near the border with South Sudan.
The report released on Friday came one day after officials accused Sudan of bombing a refugee camp in South Sudan. Four bombs fell in and around a camp called Yida in Unity State. No casualties were reported.
South Sudan President Salva Kiir said on Thursday that Sudan appears to be preparing to invade the south.
The Satellite Sentinel Project said on Friday that satellite imagery appears to show the enhancement of two air bases Sudan seized in Kurmuk from rebels in Sudan`s Blue Nile State. The group says the images show three helicopter gunships and an Antonov, the plane witnesses said was used in Thursday`s bombing run of the Yida refugee camp.
