The bitter harvest of Ethiopia's war in the Tigray region

Having joined the Tigray People's Liberation Front (TPLF) around the time of its formation in 1975, Asmelash lost his eyesight when he was bombed in his hideout in the Imba Alaje mountain during the war that ended with the guerrilla movement marching into Ethiopia's capital, Addis Ababa, to seize power from the notorious Mengistu Haile Mariam regime in 1991.

Then in 1998, when the TPLF-led government found itself at the centre of a border war with Eritrea, Asmelash lost his left arm in an airstrike on the regional capital, Mekelle.

In the latest conflict that has seen the TPLF return to being a guerrilla movement, Asmelash - who was a member of its executive - was killed along with two other TPLF veterans - former foreign minister Seyoum Mesfin and former minister of federal affairs Abay Tsehaye.

Ethiopia's 44-year-old Prime Minister Abiy Ahmed - who ordered the military operation that ultimately led to their deaths - was a junior member of the TPLF-led coalition government until his rise to power in 2018.

Now, he and the TPLF are enemies fighting for control of Tigray, a strategically important region which borders Sudan and Eritrea, the gateway to the shipping routes of the Red Sea.

Eritrea's President Isaias Afwerki has reportedly sent troops to Tigray to bolster the Ethiopian military's operation and, some say, to avenge his humiliation at the hands of the TPLF during the 1998-2000 border war that left up to 100,000 people dead.

Both governments deny Eritrean troops are in Tigray, despite many Tigrayans, Eritreans and the US government saying they are there.

Mr Abiy declared victory over the TPLF following the capture of the regional capital, Mekelle, on 28 November, but vowed that efforts to apprehend the TPLF "clique" - which was estimated to have 250,000 fighters under its command - would continue.

How Asmelah, Seyoum and Abay - all aged over 60 - died is unclear: some allege they were shot dead in cold blood, but the official Ethiopian version is that they were killed in a cave area after they refused to surrender.

Their deaths came on top of the capture of several other TPLF stalwarts - including Sebhat Nega, who was paraded in front of the cameras in handcuffs and looking dishevelled, in a scene reminiscent of the capture of Iraq's former ruler Saddam Hussein in 2003.

Faisal Roble from the US-based Institute for Horn of Africa Studies and Affairs said that supporters of Mr Abiy are celebrating the fate of the men who belonged to an organisation that had ruled Ethiopia with an iron hand until mass protests forced it to relinquish power to Mr Abiy nearly three years ago.

"They are saying: 'We got the TPLF. We are destroying it. They will never be able to oppress us again.'

"But Tigrayans - including those who never liked the TPLF - are saying: 'You killed Asmelash, a blind man, Seyoum, who had back surgery and struggled to walk, Abay, who had heart surgery, and you humiliated Sebath, who can't walk up two stairs. These are our heroes.'"

Exiled Eritrean human rights campaigner Paulos Tesfagiorgis said there was no doubt that almost three months into the conflict, the TPLF has suffered major setbacks after being hit by drone strikes and the massive deployment of Ethiopian and Eritrean troops, as well as forces from Ethiopia's Amhara region, which under the country's federal system has its own land dispute with Tigray.

"The TPLF has lost a lot of ground, a lot of leaders, a lot of fighters, and a lot of heavy weaponry. It now has only medium and light weapons. I don't think it expected Eritrea to get involved to the extent it has.

"Isaias has pursued his old strategy of overwhelming the enemy with troops, tanks, armament, and bombings," Mr Paulos said, adding: "But the TPLF is not finished. It fought intense battles. Now, it has returned to familiar ground, the rural areas of Tigray, its mountains and hills, to wage a guerrilla war."

Menychle Meseret, an academic at Ethiopia's University of Gondar, said the TPLF's move to guerrilla warfare, after waging a "full-scale" conflict against the Ethiopian military, posed its own dangers.

"With insurgent groups, even one suicide bomber can cause a lot of deaths. In the case of the TPLF, it has some remaining fighters. There are reports of fighting in some mountainous areas, and of the TPLF having already carried out ambushes on roads - even on an aid convoy."

Mr Paulos said he believed that the government was using starvation as a weapon of war.

"Government soldiers burnt the crops of Tigrayans; the offensive happened during the harvest season, and slaughtered their livestock. This was happening while the government imposed a total blockade on Tigray. No food was getting in. Even now, the flow of aid is heavily restricted.

"People are already dying of hunger. There are warnings of a famine. This is a war waged without compassion. It reminds me of Mengistu's quote: 'To kill the fish, drain the pond'." In order to weaken the TPLF, Abiy's government has to subdue the civilians, including subjecting them to hunger," Mr Paulos said.

Aid agencies have reported that the conflict - which came amid the coronavirus pandemic and a locust infestation of crops - had caused a "dire" situation:

An official in the newly appointed administration in Tigray was quoted by local media as saying that the crisis in the region was "unprecedented in its history". He put the number who required emergency food aid at 4.5 million (up to 75% of the population), the number of displaced at 2.5 million, and said his office had received reports of 13 people - including three children - having died of hunger.

The government has denied using starvation as a weapon of war, and Mr Menychle said such accusations were "completely wrong".

"The government has enough food stocks but it can't deliver them in rural areas because the TPLF is killing drivers. The TPLF wants to orchestrate starvation as a weapon to manipulate global opinion and get sympathy for its cause.

"The TPLF gave guns to farmers, and forced some of them to fight. That is why crops ended up being destroyed. The TPLF also controlled the government administration of all towns. It destroyed offices - even hospitals - before it abandoned towns," Mr Menychle said.

The state-linked Human Rights Commission said that residents of the agricultural hub of Humera in western Tigray had reported widespread looting of houses and businesses by an ethnic Amhara youth group, militias, special forces, as well as some Ethiopian and Eritrean soldiers.

"Looters have also emptied food and grain storages," it said, adding that a resident had complained that even people sent by the newly appointed administration to help them "take part in theft".
