African leaders attempted Monday to kickstart some kind of mediation in Ethiopia's escalating internal conflict, two days after rocket strikes on Eritrea's capital highlighted risks that fighting could spread.
Ugandan President Yoweri Museveni held talks with Ethiopia's deputy prime minister Demeke Mekonnen, while former Nigerian president Olusegun Obasanjo headed to Addis Ababa to make his bid for dialogue.
Ethiopian Prime Minister Abiy Ahmed announced November 4 he had ordered military operations in Tigray in a dramatic escalation of a long-running feud with the region's ruling party, the Tigray People's Liberation Front (TPLF).
Hundreds of people are reported to have been killed so far in the conflict in Africa's second most populous country, some in a gruesome massacre documented last week by Amnesty International.
More than 25,000 Ethiopians have fled into Sudan, Sudanese officials say.
"A war in Ethiopia would give the entire continent a bad image," Museveni wrote on Twitter after meeting Demeke in the northern town of Gulu.
"There should be negotiations and the conflict stopped, lest it leads to unnecessary loss of lives and cripples the economy."
But Museveni later deleted the tweet, and an Ethiopian official said Demeke made clear negotiations weren't an immediate possibility.
"We don't need mediation until we bring ringleaders to court," Redwan Hussein, spokesman for a crisis committee set up to respond to hostilities in Tigray, told reporters in Addis Ababa.
"Any mediation would incentivise impunity and unruliness."
Redwan added that Demeke would soon deliver the same message to Kenyan President Uhuru Kenyatta and other East African leaders.
Meanwhile Nigeria's ex-president Obasanjo on Monday left for Addis Ababa to mediate in the crisis, his spokesman said, without giving further details.
Both Abiy's office and the African Union said Monday they did not have information about Obasanjo's visit.
Abiy's office also denied any steps towards mediation were taking place in Uganda.
TPLF leader Debretsion Gebremichael told AFP Monday he was "not aware" of Museveni's initiative.
Abiy's government has said the TPLF needs to be disarmed before negotiations can begin, as world leaders have called for an immediate end to hostilities.
"The fact of the matter is that it is the TPLF which has violated the constitution and endangered the constitutional order," the upper house of parliament said in a statement Monday.
"The federal government is merely working towards restoring it."
Ethiopian generals have vowed to keep military operations contained in Tigray, and Abiy has repeatedly vowed to deliver a quick, decisive victory.
Last week Abiy said federal forces had "liberated" the western zone of the Tigray region, which is made up of six zones plus the capital, Mekele, and surrounding areas.
On Sunday state media reported that federal forces had seized Alamata, a town 180 kilometres south of Tigray.
"As the TPLF militia were defeated in Alamata, they fled taking along around 10,000 prisoners," a government statement said.
A communications blackout in Tigray has made claims of advances difficult to verify.
The threat of fierce resistance from TPLF-aligned fighters "persists as the Tigray special forces have access to military assets and troops from the (national army) have defected to Tigray," said Sanya Suri, East Africa analyst at the Economist Intelligence Unit.
However Suri predicted federal forces "will succeed in quashing the conflict in Tigray in the near term", albeit with "severe" casualties on both sides.
In recent days the TPLF has extended the conflict beyond Tigray, launching rockets on airports in Ethiopia's Amhara region, which borders Tigray to the south, and in the capital of Eritrea, Ethiopia's neighbour to the north.
Debretsion has said the strikes are "legitimate" because federal forces are using the airports as part of their military operations in Tigray.
The strikes on the Eritrean capital Asmara in particular have reinforced fears that Ethiopia's conflict could draw in the wider Horn of Africa region.
The TPLF has accused Abiy's government of enlisting military support from Eritrea, something Ethiopia denies.
At Monday's press conference, Redwan, the crisis committee spokesman, indicated the government held the TPLF responsible for the humanitarian fallout and accused it of deliberately spurring a refugee crisis.
"They are trying to scare the Tigrayan people so that they can flee away from home and go to other areas, because then they can create a humanitarian crisis, which might also trigger international attention."
