Ethiopia's Amhara state on Sunday called on "all young people" to take up arms against Tigrayan fighters who are battling the federal government military and forces from all of Ethiopia's other nine regions.
The call for mass mobilization against Tigray People's Liberation Front (TPLF) fighters - whom Amhara's military said were now attacking the state - expands the eight-month-old war and instability in the Horn of Africa country.
"I call on all young people, militia, non-militia in the region, armed with any government weapon, armed with personal weapons, to join the anti-TPLF war mission from tomorrow," Agegnehu Teshager, president of Amhara regional government was quoted as saying by the region's state media.
Calls to TPLF spokesman Getachew Reda, for a comment were not answered.
War erupted between the Ethiopian military and the TPLF, which rules Ethiopia's northernmost region, in November.
Three weeks later, the government declared victory when it captured Tigray's capital Mekelle, but the TPLF kept fighting. At the end of June, the TPLF seized control of Mekelle and most of Tigray after government soldiers withdrew.
This week, the Tigrayans pushed their offensive to Afar, their neighboring state to the east, where they said they planned to target troops from the Amhara region fighting alongside the federal military in the area.
Afar is a strategic region for landlocked Ethiopia because the main road and railway linking the capital, Addis Ababa, with the seaport of Djibouti runs through it.
On Saturday, Amhara's special forces commander, Brigadier General Tefera Mamo, was quoted by the region's state media as saying the war had expanded to the state.
"The terrorist group has started a war in the Amhara and Afar regions and is also harassing Ethiopians," Tefera said, referring to TPLF. "Amhara Special Forces are fighting in coordination with other security forces."
Thousands of people have died in the fighting, around 2 million have been displaced and more than 5 million rely on emergency food aid.
