Ethiopia's military has killed more than 40 men suspected to be linked to the massacre of at least 100 people, including children, in the Benishangul-Gumuz region, state media report.

Five current and former government officials were also detained over the security crisis, the reports added.

The assailants torched the homes of sleeping villagers, and shot and stabbed people in Wednesday's attack.

The attack came a day after Prime Minister Abiy Ahmed visited the region.

It is unclear who the attackers were, but they appeared to have targeted ethnic minority communities viewed as “settlers” in the region, rights group Amnesty International said.

Ethiopia has seen a surge in political, ethnic and religious violence in recent years.

It had the highest number of internally displaced people in Africa in 2018 – about 1.8 million.

Conflicts have been largely fuelled by groups demanding more land and power, with attempts to drive out people they regard as outsiders.

Mr Abiy described the massacre as tragic, and said the government had deployed a force to the area to help find a solution to the conflict.

State media did not give the identity of the 42 people killed in the military operation to hunt down the attackers.

It said weapons, including bows and arrows, had been seized, the reports said.

A deputy minister in the government was among the five people arrested, state media reported.

Some of the five were “supposedly involved in [the] security crisis” while others had been detained because they had “not fulfilled their responsibility appropriately”, the reports said. (BBC)
