The UN has condemned an Ethiopian government air strike that killed at least four people, including two children on Friday.

UNICEF says the attack hit a kindergarten in Mekelle, the regional capital of Tigray.

The government has denied targeting civilians. On Saturday, federal forces withdrew from Kobo, a city just south of Tigray.

The conflict between the rebels and government forces began nearly two years ago.

A ceasefire was agreed this year – but fighting resumed last week.
