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.

After some missed calls, President Joe Biden finally connected with the parents of Wall Street Journal reporter Evan Gershkovich, White House press secretary Karine Jean-Pierre confirmed Tuesday.

"He felt it was really important to connect with Evan's family," she told reporters on Air Force One as the president travels to Ireland.

Meanwhile, National Security Council spokesperson John Kirby said Gershkovich's detention is "pretty fresh" and officials are still trying to get consular access to Gershkovich, which they have not been able to do.

He would not get into any specific conversations the U.S. is having with Russians about releasing Gershkovich or if a prisoner swap is a possibility.

"I just want to make a couple of things clear that is, the determination of wrongful detention, it doesn't start the clock necessarily on communicating with the Russians about getting him released," Kirby said. "We're very early in this process here and I certainly, I think you can understand why I wouldn't talk about any discussions we might be having with the Russians about his release or Paul [Whelan]'s release. We certainly wouldn't do that."

Kirby said the administration is "certainly having discussions about what we can do to get him released."

"I don't want to go into details about these internal deliberations, having things out in the public sphere viscerally might actually make it harder to get Evan and Paul home, and that's what we're focused on," Kirby said.
