BRUSSELS (AP) — Since Russian President Vladimir Putin ordered the invasion of Ukraine in 2022, NATO has focused on trying to deter an attack on its own territory and avoid all-out war with nuclear armed Russia. Now the time has come for NATO to defend itself, and European allies might have to do it alone, experts and leaders say.

Russian drones breached Poland’s airspace and, experts said, by Kremlin design or not, the incident tested NATO’s readiness to defend its easternmost members.

Ukrainian drones attacked the Russian Black Sea coast overnight into Tuesday morning, according to the Russian Defense Ministry and local officials.

Ukraine's crowdfunding groups say they've found the winning formula for beating Russia. But they're often overlooked.

An infant was among three people who died in Russia's overnight attacks on Kyiv that injured 18 and set on fire scores of buildings in the capital, including the seat of the government, Ukrainian officials said on Sunday.
