Ethiopia's cabinet on Tuesday declared a nationwide state of emergency after Tigrayan rebels seized two crucial towns in an apparent push towards the capital, state-affiliated media reported.
"The state of emergency is aimed to protect civilians from atrocities being committed by the terrorist TPLF group in several parts of the country," Fana Broadcasting Corporate reported, referring to the Tigray People's Liberation Front.
Lawmakers are expected to approve the measure within 24 hours, Fana said.
In recent days the TPLF has claimed control of two key cities about 400 kilometres from Addis Ababa and has not ruled out marching on the capital, which has so far not seen any fighting.
The government has denied claims of TPLF territorial gains which, if confirmed, would represent a major strategic advance.
Much of northern Ethiopia is under a communications blackout, and access for journalists is restricted, making battlefield claims difficult to verify independently.
Earlier on Tuesday, officials ordered Addis Ababa residents to register their firearms and prepare to defend their neighbourhoods.
Prime Minister Abiy Ahmed sent troops into Tigray a year ago to detain and disarm the TPLF, a move he said came in response to attacks on army camps.
The 2019 Nobel Peace laureate promised a swift victory, but by late June the rebels had regrouped and retaken most of Tigray.
They then launched offensives into the neighbouring regions of Afar and Amhara.
The international community has expressed alarm at the expanding conflict, with Western powers reiterating calls for an immediate ceasefire and for the African Union to broker peace talks between the warring parties.
