Estonia has said a Nato fighter jet shot down a drone, which it suspects was a Ukrainian projectile knocked off course by Russian electronic jamming, over its territory. Defence Minister Hanno Pevkur said a Romanian F-16 fired a missile and drone debris fell in a marshy area in central Estonia on Tuesday. Ukraine reacted by accusing Russia of deliberately redirecting Ukrainian drones launched at legitimate military targets in Russia, apologising to Estonia and all of our Baltic friends for such unintended incidents. Russia has not commented on the latest in a series of recent drone incursions over Nato members Estonia, Latvia and Lithuania. Last week, Latvian Prime Minister Evika Silina resigned following a political crisis over Russia-bound Ukrainian drones straying into Latvian territory.

Inside the'kill-zone' on Ukraine's front line, where new weapons have transformed war After 225 days stuck in a front-line foxhole, the Ukrainian infantryman's muscles were so weak he could barely walk. His commanders had tried five times to swap him with another soldier - but they could never reach him. Rotating soldiers on the front line in eastern Ukraine is extremely difficult because of the constant threat of drones. This area near Kostyantynivka is currently one of the most dangerous hotspots and the Ukrainian military admits that Russian forces have reached its outskirts. Known as Kenya, the infantryman took two days to walk 11km (6.8 miles) to get back to his brigade, avoiding mines and hiding from drones to get out.

Three people were killed overnight in a large-scale Ukrainian drone attack on the Moscow region, Russian officials have said. A woman died in a house in Khimki, north of the capital, where a person was trapped under rubble, regional governor Andrei Vorobiev said. A man and a woman were killed in the village of Pogorelki. Moscow Mayor Sergei Sobyanin said 12 people were injured in strikes on a city oil refinery. Russia's military said 556 drones were intercepted.

Latvian Prime Minister Evika Silina has resigned following a political crisis over Russia-bound Ukrainian drones straying into Latvian territory. She had fired her Defence Minister Andris Spruds last week after two drones crashed down in eastern Latvia, criticising his response and appointing a replacement. In protest, Spruds's Progressives party pulled their support for Silina's governing coalition, causing it to collapse months before a planned general election in October. Seeing a strong candidate for the post of defence minister... political windbags have chosen a crisis, Silina said on Thursday. I am resigning but I am not giving up.

Are drones, AI making it harder to fight armed groups in the Sahel? The brazen attack on the international airport and nearby military airbase in Niamey, Niger's capital, came overnight between January 28 and 29. Balls of orange fire flew across the sky as the Nigerien army attempted to respond while residents ducked for cover and whispered prayers, as shown in videos on social media. ISIL (ISIS) in Sahel Province, or ISSP - a Niger-based outfit earlier known as the ISIL affiliate in the Greater Sahara or ISGS - has since claimed responsibility and says it killed several soldiers, although the Nigerien army disputes this. Many of its fighters had breached military drone hangars using RPGs and mortars, and managed to damage several aircraft and one civilian aeroplane, according to videos from the group.

However, searching the adversarial state is challenging due to the large, discrete, and non-differentiable search space.

Drone strikes in Ethiopia's Tigray kill one amid fears of renewed conflict One person has been killed and another injured in drone strikes in Ethiopia's northern Tigray region, a senior Tigrayan official and a humanitarian worker said, in another sign of renewed conflict between regional and federal forces.

A local humanitarian worker confirmed the strikes had happened. Both asked not to be named, the Reuters news agency reported. It was not immediately clear what the trucks were carrying.
