The UN says it is increasingly concerned about the plight of civilians in Ethiopia’s Tigray region and has once again called on the government to allow full access so that allegations of war crimes can be investigated.

The UN High Commissioner for Human Rights, Michelle Bachelet, said two humanitarian assessment missions were able to enter the region on Monday.

But she said due to restrictions it had not yet been possible to investigate allegations of artillery strikes on populated areas, extrajudicial killings and widespread looting.

The UN said it had received consistent reports of artillery strikes last month on homes and a hospital in the town of Humera on the border with Eritrea
