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.

The U.S. will announce another assistance package for Ukraine on Friday, White House spokesperson John Kirby announced Thursday afternoon, but did not detail the exact size of this next round of support.

"You'll see us tomorrow, just unilaterally, the U.S. will have another round of assistance for Ukraine coming tomorrow. And it will include mostly ammunitions and munitions that the Ukrainians will need for the systems that they already have, like the HIMARS and the artillery."

The new aid comes as President Joe Biden meets with German Chancellor Olaf Scholz at the White House Friday to discuss ongoing support for Ukraine as Russia's invasion continues.

Kirby said the leaders would discuss the "kinds of capabilities that Ukraine continues to need in the weeks and months ahead."

He also said this will be a "true working visit" between Biden and Scholz and they are expected to discuss "recent engagements with Ukrainian officials, including the President's trip to Kyiv and meeting with President Zelenskyy, as well as Chancellor Schultz’s meeting with President Zelensky in Paris last month."
