Finland will formally join NATO in the "coming days," after the country was able to clear its final hurdle, according to NATO Secretary General Jens Stoltenberg.

"Their membership will make Finland safer and NATO stronger. Finland has highly capable forces, advanced capabilities and strong democratic institutions. So Finland will bring a lot to our alliance," Stoltenberg said in a statement Friday.

Turkey was the last of the 30 NATO allies to approve Finland's bid to join the alliance.

Russia just struck Kharkiv in eastern Ukraine with multiple missiles, Ukrainian officials said Thursday night.

Local officials in Kharkiv said Russia fired six Soviet-era S-300 surface-to-air missiles.

ABC News reporters heard explosions outside the city center and saw Ukrainian air defense active just before and during the attacks.

There are currently no reports of casualties or damage to infrastructure as a result of the strikes in Ukraine's second-largest city.

There are also reports of Russian strikes in the Dnipro region.

Russian media reporting suggests authorities are preparing to start a major military recruitment aiming to sign up an additional 400,000 troops, the United Kingdom's Defense Ministry assessed.

Russia is presenting the campaign as a drive for volunteer, professional personnel, rather than a new, mandatory mobilization. There is a realistic possibility that in practice this distinction will be blurred, and that regional authorities will try to meet their allocated recruitment targets by coercing men to join up, UK officials said.

Russian authorities have likely selected a supposedly ‘volunteer model’ to meet their personnel shortfall in order to minimize domestic dissent. It is highly unlikely that the campaign will attract 400,000 genuine volunteers, according to UK officials.

However, rebuilding Russia’s combat power in Ukraine will require more than just personnel; Russia needs more munitions and military equipment supplies than it currently has available, UK officials said.

Chinese President Xi Jinping hadn't even left Moscow when the drones started exploding. It came a matter of hours after Xi and Russian President Vladimir Putin proclaimed they were the ones who wanted to make "peace" in Ukraine.

Ukrainian officials say 21 lethal attack drones were launched overnight and into this morning by Russia, with 16 shot down by the Ukrainians.

An apartment block was hit in a town southeast of Kyiv, killing at least four people and injuring others, officials said. Russian officials claim Ukrainian soldiers were based there. The Ukrainians are calling it a "civilian" building.

Russian missiles later hit an apartment block in the heart of the southern Ukrainian city of Zaporizhzhia.

And in an apparent repost to the geopolitical theatrics in Moscow, Ukrainian President Volodymyr Zelenskyy visited his troops on Wednesday in the eastern Donbas, not far from the embattled city of Bakhmut, according to his officials.

Bakhmut has become a potent symbol of Ukrainian resistance and sacrifice and despite being surrounded on three sides Ukrainian forces inside the city are, after months of fighting there, still holding on.

Zelenskyy's office released video of him addressing troops and also visiting injured soldiers in a military medical facility in the region. He told troops their "destiny was difficult but important" because they were fighting to save the motherland.
