MAKELLE, Ethiopia, April 24 An explosion at a cafe in Ethiopia's northern region of Tigray killed five people on Saturday and wounded 20 others, officials said, blaming the attack on neighbouring Eritrea.
"This is an attack by the Eritrean government to deliberately disrupt the upcoming elections," said Micheal Abraha, Tigray's administrator.
Ethiopia is scheduled to hold national elections on May 23.

The two Horn of Africa neighbours have had long running hostilities and tensions simmer along their common border due to a dispute over the frontier.
Relations have been at an impasse since they fought a 1998-2000 war in which at least 70,000 people were killed.
Tigray's regional president, Tsegay Berhe, said Eritrean agents sneaked into the country and were responsible for the attack.
"Ethiopian elections won't be disrupted despite Eritrea's attempts to do so," he said.
There was no immediate comment from the Eritrean government. (Reporting by Tesfa-Alem Tekle; Editing by Helen Nyambura-Mwaura)
