Mounting worries exist regarding the possibility of warfare between Horn of Africa neighbors, the Ethiopian government and the Eritrean government, as aggressive rhetoric has escalated in the last month.
Ethiopia's, being landlocked, demands for entry to the Red Sea through Eritrean territory has triggered a fierce rhetorical conflict.
The Ethiopian leader first openly declared in 2023 that his nation's access to the sea was an existential matter, comments that Eritrea ignored.
Diplomatic connections between the both governments have regularly been difficult. After a long-standing battle for independence, Eritrea, which has a 1,350km (840-mile) maritime frontage, officially seceded from Ethiopia in 1993, rendering it cut off from the sea.
Five years later, a territorial conflict erupted in which more than 100,000 people died.
Abiy and army chief the army commander have openly claimed ownership of Eritrean coastal city of the port of Assab – some 60 km from the boundary - and hinted at the intention to take it by force.
In early September, Abiy said Ethiopia's "blunder" of being denied passage to the sea as a due to Eritrea's separation would be "corrected in the future".
The Ethiopian envoy to neighboring Kenya, retired Gen Bacha Debele, said that Assab was "belonging to Ethiopia" and would be given back "by force".
In the face of ongoing warnings from Ethiopian officials, Eritrea's reaction has been confined to short statements on social media from Information Minister Yemane Gebremeskel.
Officials have denied Ethiopia's push for sea access calling it "dangerous" and a "harmful plan" of "territorial claims" – a approach of reclaiming previous domains.
The information ministry alerted on recently that attempts to justify "obvious provocation" would have significant repercussions for the Ethiopian government and its neighbors and is a "redline that should not be crossed|violated|breached".
So far, there are few indications of large-scale army activities in the frontier regions between the neighboring states.
Nevertheless, in the country, state television has shown completion events of thousands of cadets at different defense facilities.
The head of human resources department of the military, Lt Gen Hachalu Sheleme, stated recently in an conversation that the military was in a "reliable position" as "numerous of young people" were enlisting, which he said was "a warning to our enemies".
For over fifty years from 1890, the territory was administered by Italian rulers.
Following the end of Italian rule, it was then administered by the British administration before becoming a associated territory of Ethiopia.
But in 1962 the Ethiopian emperor cancelled this agreement and the region became fully incorporated into Ethiopia.
A extended internal conflict ensued, ending with the government's loss in 1991. Autonomy was then approved by Eritreans in a plebiscite in 1993.
Briefly in the 1990s, there were positive ties between the governments in Addis Ababa and Eritrea's capital, but they clashed over the precise positioning of their common border, resulting in war in 1998.
Though this ended in a peace deal in 2000, it was incompletely executed, and the neighbors remained at odds.
This changed in 2018, when Abiy made approaches to Eritrea's leader Isaias Afwerki. The two endorsed a declaration that the war was concluded – a decision that earned the Prime Minister the prestigious award.
The both administrations were then cooperators in Ethiopia's previous civil war in the northern region.
But diplomatic connections have since broken down anew.
