Denise Brown, the UN resident and humanitarian coordinator in Sudan, said that there has been an intense pattern of drone strikes over the past couple of weeks against civilian infrastructure, with sources of energy and fuel apparently systematically targeted.

At a hospital just outside Khartoum, the power went out and stopped treatment for 25 patients who needed dialysis; the hospital has no generator and no solar panels. Hundreds of aid trucks are stuck for lack of fuel, and there are queues kilometers long for fuel in the capital. The World Food Programme has recorded seven hits on its convoys this year and 20 over the past two years. Brown said she did not know where the strikes originate and called for the message that they must stop to reach whoever needs to hear it.
