ADDIS ABABA, Ethiopia — The general suspected of being behind a coup attempt in the Ethiopian region of Amhara has been captured and killed, state media reported on Monday.

The suspect, Gen. Asamnew Tsige, was accused of planning gun attacks on Saturday night that killed four people, including the army’s chief of staff and Amhara’s regional president. A fifth victim, the attorney general of Amhara, died of his wounds on Monday.

Earlier Monday, an Ethiopian government spokesman said that security forces were hunting General Asamnew but that a number of other plotters had been arrested.

In one attack in the coup attempt, the army chief of staff, Seare Mekonnen, and a retired general, were shot by Mr. Seare’s bodyguard at his home in the national capital, Addis Ababa, the prime minister’s office said.
