Abiy orders military operation in Tigray
Prime Minister Abiy Ahmed ordered a military response to what he called a "traitorous" attack on federal army camps in Tigray, which he blamed on the TPLF, AFP reported.
War between Ethiopia's federal government and the Tigray People's Liberation Front began in November 2020 and ended with an African Union brokered cessation of hostilities signed in Pretoria on 2 November 2022. Estimates of the dead range from under 100,000, cited by some Ethiopian officials, to about 600,000, cited by the AU's lead mediator. After a split in the TPLF in 2025 and the party's deregistration, renewed fighting broke out on 23 September 2026.
Fighting between federal forces and an alliance that includes the TPLF broke out on 23 September 2026. Federal forces and an allied militia took Mekelle in early October after the TPLF withdrew and entered Adwa on 11 October. On 16 October Abiy named a new interim administration for Tigray to serve for six months ahead of elections, Reuters and AFP reported.

After Tigrayan forces pushed into the neighbouring Amhara and Afar regions, Ethiopia declared a nationwide state of emergency, AFP reported.
A joint investigation by the UN Human Rights Office and the Ethiopian Human Rights Commission, covering November 2020 to 28 June 2021, found reasonable grounds to believe that all parties had violated international law, and that some violations may amount to war crimes and crimes against humanity.

African Union led peace talks between the federal government and the TPLF began in Pretoria, AFP reported.
The two sides signed an agreement for a permanent cessation of hostilities. Under the text, the TPLF was to complete its disarmament, including light weapons, within 30 days, federal authority was to be restored in Tigray, an interim regional administration settled through dialogue was to govern until elections, and the government was to facilitate the lifting of the TPLF's terrorist designation. A joint committee chaired by the AU was to monitor implementation. The text does not name Eritrea.
Olusegun Obasanjo, the African Union's lead mediator, told the Financial Times that about 600,000 people had been killed, The National reported. It said some Ethiopian officials put the figure under 100,000.

A TPLF faction led by former regional leader Debretsion Gebremichael took control of Mekelle's FM radio station and the mayor's office, two days after taking Adigrat, BBC News reported. Getachew, who was in Addis Ababa, accused the faction of trying to remove him by force and of colluding with Eritrea, which Eritrea denied.
Abiy appointed Tadesse Werede, deputy head of the interim administration and a former senior TPLF commander, to lead it, Reuters reported. Getachew's two-year term had expired, Reuters said.
The National Election Board of Ethiopia revoked the TPLF's legal status, saying it had failed to meet its registration obligations, the state Ethiopian News Agency reported. BBC News said the failure to hold a general assembly was cited. In a letter to the African Union, the TPLF said the ban threatened the peace process and asked the AU to press the government to suspend it.
The TPLF said at the end of April 2026 that it had reinstated the regional parliament that had been suspended under the peace agreement, AFP reported.

Getachew Reda, by then minister of East African affairs, and intelligence chief Redwan Hussein wrote in an opinion piece on Al Jazeera's website that hardline TPLF elements planned to attack the federal government with Eritrean help, AFP reported. AFP said direct clashes had resumed in late 2025. The TPLF did not respond to AFP.
Fighting broke out after seven armed and political groups, including the TPLF, announced an alliance aimed at removing Abiy's government, Al Jazeera reported.
