Ethiopian officials threaten to send troops back into Tigray

Warning comes less than 48 hours after unilateral ceasefire declared by Addis Ababa

Ethiopian military and diplomatic officials have threatened to send troops back into Tigray less than 48 hours after announcing that Addis Ababa had declared a unilateral ceasefire in the devastated northern province.

The announcement on Wednesday that Ethiopian federal forces would withdraw from Tigray caught many observers by surprise, and signals a major shift in strategy. However, the new threat underlines the fragility of any current calm.
