Ethiopian officials say one person has died and dozens more are injured, after an explosion at a rally for the new PM Abiy Ahmed.
Earlier Abiy had said that several people had died.
Abiy described it as an "unsuccessful attempt by forces who do not want to see Ethiopia united".
He was whisked away immediately after the blast, thought to be from a grenade thrown amid thousands of people in Addis Ababa's Meskel Square.
Ethiopia's health minister tweeted that one person had died and 154 were injured, 10 of them critically.
Abiy only became prime minister after his predecessor Hailemariam Desalegn unexpectedly resigned in February.
