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 United States announced an additional $2 billion military aid package for Ukraine on Friday, as the Eastern European country marks the one-year anniversary of Russia's full-scale invasion.

The new aid package includes more missiles for Ukraine's U.S.-supplied High Mobility Artillery Rocket Systems (HIMARS), additional 155mm artillery ammunition, more Switchblade one-way drones and other military equipment, according to the U.S. Department of Defense.

"One year into a war of aggression waged by a permanent member of the U.N. Security Council, our allies and partners worldwide stand united and resolute," U.S. Secretary of Defense Lloyd Austin said in a statement. "Putin's reckless, illegal war is not just an all-out assault on Ukraine's sovereignty and a historic threat to European security. It is also a direct attack on the system of rules, institutions, and laws that the world built at such great cost after World War II -- a system that rejects aggression and respects the rights of all countries, big and small."

The additional aid is being provided under the Ukraine Security Assistance Initiative (USAI) plan, meaning this equipment and artillery have to be made from scratch before being delivered, which will take time. This is different from the other aid packages that come from existing U.S. military stockpiles and get delivered faster.

With the new aid package, the Biden administration has now provided $31.8 billion in assistance to Ukraine since Russia's war began on Feb. 24, 2022.

"Putin thought that Ukraine’s defenses would collapse, that America's resolve would falter, and that the world would look the other way. He was wrong," Lloyd said. "One year later, Ukraine's brave defenders have not wavered, and neither has our commitment to support them for as long as it takes. Despite the Kremlin's campaign of cruelty, the people of Ukraine have shown stunning bravery, skill, and fortitude. Today and every day, we stand by the courageous Ukrainians fighting to defend their country, and we mourn with those who have lost their loved ones in Moscow's monstrous and unnecessary war."

"Difficult times may lie ahead, but let us remain clear-eyed about what is at stake in Ukraine," he added. "And let us remain united in purpose and in action -- and steadfast in our commitment to ensure that a world of rules and rights is not replaced by one of tyranny and turmoil."
