Despite hopes for a ceasefire in Tigray region last month, the Ethiopian conflict is expanding. The Oromo Liberation Army (OLA), the main rebel group in the country's largest region, Oromia, warned on Aug. 14 that it is close to cutting off a major highway to Kenya—a move that could disrupt trade with the largest economy in East Africa. Having announced a pact with the government's arch-adversary, the Tigray People's Liberation Front, the OLA claims it is advancing on the western and southern fronts of Oromia region, and holds parts of the southern Borena zone bordering Kenya. Meanwhile, as the humanitarian crisis deepens and Tigrayan rebels push on into Amhara and Afar regions, there has been a relaunch of diplomatic efforts to halt the fighting. US special envoy Jeffrey Feltman arrived in Ethiopia last weekend, and Sudan's Prime Minister Abdalla Hamdok—rebuffed once by Addis Ababa—said he is still willing to mediate. Sudan, however, has its own dispute with Ethiopia over the contested al-Fashaga border region—an issue Khartoum reiterated is non-negotiable.

Chad's defense ministry charged May 30 that troops of the neighboring Central African Republic (CAR) attacked a Chadian military post, and that this amounted to a war crime. Chad's Foreign Minister Cherif Mahamat Zene said: "The Central African armed forces attacked the outpost of Sourou in Chad [and] killed a Chad soldier, injured five and kidnapped five others who were then executed in Mbang on the Central African Republic side."

Armenia's Security Council held an emergency meeting May 12 in response to a reported border incursion by Azerbaijan. Local authorities in southern Syunik province issued urgent reports that Azerbaijan's forces had crossed the border and completely surrounded Lake Sev. The glacial lake, which provides water for irrigation in the area, is bisected by the frontier between the two countries, with its northern third lying within Azerbaijan. But the territory on the Azerbaijan side had been held by Armenia between the 1991-4 war and last November's ceasefire, under which it was ceded back. The two sides remain at odds on the precise demarcation of the line, which had not been formalized in Soviet times.

The armed forces of Kyrgyzstan and Tajikistan clashed at a disputed section of their border on April 29, leaving 30 dead and thousands displaced before a ceasefire was declared. The fighting broke out near the strategic Golovnoi (also rendered Golovnaya) water pumping facility, in the Tajik-controlled exclave of Vorukh. Kyrgyz protesters gathered on their side of the de facto border after Tajik authorities installed surveillance cameras at the facility. The two sides began hurling rocks at each oher across the line before military troops intervened, and the situation escalated. The Golovnoi facility pumps water from the Isfara River, a tributary of the Syr Darya, to irrigate agriculture in the area. It is in the Fergana Valley, a small fertile pocket in the arid Central Asia region. Soviet authorities drew the boundaries so that Kyrgyzstan, Tajikistan and Uzbekistan each got a portion of it. However, this meant intricate, twisting borders between these nations, and territorial disputes have arisen.

The International Tribunal for the Law of the Sea ruled Jan. 28 that the United Kingdom does not hold sovereignty over the Chagos Islands, allowing the dispute between Mauritius and Maldives in regards to the delimitation of their boundaries to proceed. The ruling follows a preliminary objection from the Maldives government, which claimed that the tribunal could not decide the matter due to the existing dispute between Mauritius and the United Kingdom regarding the sovereignty of the archipelago. The tribunal rejected the objection.

In a victory for the Trump White House, Sudan has officially signed on to the so-called "Abraham Accords," agreeing to peace and normalization of diplomatic ties with Israel. Justice Minister Nasredeen Abdulbari signed the document in the presence of US Treasury Secretary Steven Mnuchin Jan. 6. While Khartoum announced its intent to join in late October, the government waited to formally proceed until the US removed Sudan from its list of "state sponsors of terrorism" last month. Sudan paid $335 million in compensation to US victims of terrorism and their families as a condition of the removal process.

US-mediated talks opened Oct. 14 between Israel and Lebanon, aimed at resolving the long-standing maritime border dispute between the two countries. At issue in the talks, held in Lebanon's coastal border town of Naqoura, is an 860-square-kilometer patch of the Mediterranean Sea where each side lays territorial claim. The conflict stems from differing demarcation methods: Israel marks the border as being at a 90-degree angle to the land border, while Lebanon marks it as a continuation of the land borderline. The issue grew more pressing with the discovery of abundant hydrocarbon reserves in the Eastern Mediterranean's Levant Basin. Lebanon, which sought to pursue gas drilling off its coast, submitted its demarcation of the maritime borders to the UN a decade ago, claiming this area as within its Exclusive Economic Zone. Israel called this an infringement of its rights, and submitted its own version of the border demarcation to the UN.

At least 16 have been killed on both sides in ongoing clashes that broke out along the border of Armenia and Azerbaijan July 12. An Azerbaijani general is among the dead in the heaviest fighting between the two nations in years. The skirmishes are mostly being fought with heavy artillery and drones. Villages in Azerbaijan's northern Tovuz rayon (district) have come under artillery fire by Armenian forces, causing property damage. (AP, Axar.az)
