Sudan's 72-hour ceasefire that went into effect on Tuesday is only partially respected. Evacuations of foreigners and civilians fleeing the country continued on Wednesday.

More than 459 people have been killed and more than 4,000 wounded since the beginning of fighting on 15 April, according to the UN. Up to 270,000 people could still be fleeing to neighbouring Chad and South Sudan, the UN says. The conflict risks "pervading the entire region and beyond," UN Secretary-General Antonio Guterres has warned.
