Ethiopia’s new PM Abiy Ahmed says several people have been killed in an explosion that hit a rally he was speaking at earlier on Saturday.
He described it as an “unsuccessful attempt by forces who do not want to see Ethiopia united”.
Mr Abiy was whisked away immediately after the blast, thought to be from a grenade thrown amid thousands of people in the capital’s Meskel Square.
Ethiopia has been riven by years of sometimes violent protests.
Mr Abiy only became prime minister after his predecessor Hailemariam Desalegn unexpectedly resigned in February.
He is the country’s first leader from the ethnic Oromo group, which has been at the centre of nearly three years of anti-government protests that have left hundreds of people dead.
One of their main complaints is that they have been politically, economically and culturally marginalised for years, despite being the country’s largest group.
