Addis Ababa, Ethiopia, Nov 17 โ The UN said Tuesday that a full-blown humanitarian crisis was unfolding in northern Ethiopia, where thousands of people each day are fleeing the conflict in the Tigray region.
The warning came as diplomats and humanitarian officials reported heavy fighting in northern and southern Tigray, and as federal forces claimed โmajor victoriesโ that would bring them closer to the regional capital Mekele.
A communications blackout in Tigray throughout the two-week conflict has made claims of advances difficult to verify.
Prime Minister Abiy Ahmed, last yearโs Nobel Peace Prize winner, announced the military campaign in Tigray on November 4, saying it came in response to attacks by the local ruling party, the Tigray Peopleโs Liberation Front (TPLF), on federal military camps.
The UN refugee agency said Tuesday that around 27,000 Ethiopians had fled across the border into Sudan โ a figure now rising by around 4,000 people each day.
โA full-scale humanitarian crisis is unfolding,โ spokesman Babar Baloch told a virtual press briefing from Geneva.
โRefugees fleeing the fighting continue to arrive exhausted from the long trek to safety, with few belongings.โ
Those arriving in Sudan recounted terrifying scenes of artillery barrages and massacres.

โI saw bodies dismembered by the explosions,โ said Ganet Gazerdier, 75, whose home was destroyed in the town of Humera, and finds herself at a refugee camp in eastern Sudan.
โOther bodies were rotting, lying on the road, murdered with a knifeโ, she added.
โ โFinal throes of deathโ โ
On Friday Abiy declared the TPLF was โin the final throes of deathโ and gave regional troops three days to โrise upโ and side with the national army.
In a Facebook post-Tuesday morning, he said their time was up and that โin the coming days the final law enforcement activities will be doneโ.

A government statement Tuesday evening said federal forces controlled multiple towns in southern Tigray and were โpacing to Mekeleโ, getting as close as Mehoni, roughly 125 kilometres (78 miles) to the south.
Federal forces already claimed to control Tigrayโs western zone, where fighting has been heavy, and over the weekend said they had seized the southern town of Alamata.
Fierce clashes occurred Tuesday in the region surrounding Alamata as well as in the northern town of Shire, where camps house thousands of Eritrean refugees, diplomats and humanitarian officials said.
Also on Tuesday, a government statement said the army had carried out โprecision led and surgical air operationsโ outside Mekele on Monday.
Tigrayan leader Debretsion Gebremichael said the strikes caused civilian casualties, which the government denied.
Diplomats say it is far from clear that federal forces will be able to quickly defeat the TPLF, which has considerable military assets and an estimated 250,000 troops fighting on mountainous terrain they know well.

The Ethiopian military is estimated at 150,000 troops, though that does not include special forces and militias.
Debretsion said Tuesday that โthe government and people of Tigrayโ would hold their ground.
โThis campaign cannot be finished. As long as the army of the invaders is in our land, the fight will continue.โ
โ Rallying support โ
Abiy has resisted calls by world leaders to cease hostilities.
His government has said there can be no mediation until Tigrayโs leaders have been disarmed and brought to court.
Abiy and his staff gathered at his office compound in Addis Ababa on Tuesday to salute the armed forces, waving flags as a military marching band played before holding their hands over their hearts during an extended moment of silence.

Similar ceremonies took place throughout the capital, with participants denouncing the TPLF.
โThe government and the people you see today didnโt come out because they like war, but they want to terminate the criminal junta once and for all,โ Addis Ababa resident Henok Lemma told AFP.
The TPLF dominated Ethiopian politics for three decades before Abiy came to power in 2018.
The military operations kicked off after months of worsening tensions as TPLF leaders were sidelined and became ever more defiant of the federal government.
In recent days the TPLF has fired rockets on airports in Ethiopiaโs Amhara region, south of Tigray, and in the capital of neighbouring Eritrea.
The strikes on Asmara, in particular, have reinforced fears that Ethiopiaโs conflict could draw in the wider Horn of Africa region.
US Secretary of State Mike Pompeo condemned the strikes while commending โEritreaโs restraint, which has helped prevent further spreading of the conflict.โ
โWe are deeply concerned by this blatant attempt by the TPLF to cause regional instability by expanding its conflict with Ethiopian authorities to neighbouring countries,โ Pompeo said.
