KYIV, Aug 20 (NHK) - The US government has announced additional military aid for Ukraine valued at up to 775 million dollars.

Officials said on Friday that the package will include ammunition for the High Mobility Artillery Rocket Systems, known as HIMARS; 16 howitzers, along with 36,000 rounds for the artillery; and high-speed, anti-radiation missiles that target radar systems.

US Secretary of State Antony Blinken said, "The courage and strength of Ukraine's military and its people are extraordinary, and the United States will continue to provide additional systems and capabilities for Ukraine."

Ukrainian President Volodymyr Zelenskyy tweeted on Friday to thank US President Joe Biden for the decision. He said, "We have taken another important step to defeat the aggressor," adding that Ukraine will be free.

The Zaporizhzhia nuclear power plant in southeastern Ukraine, which is under Russian control, has been under repeated shelling since early August. Ukraine and Russia accuse each other of the attacks.

The International Atomic Energy Agency is calling for a mission to the plant to ensure its safety.

Zelenskyy said in a video address on Friday that "Ukrainian diplomats, our partners, representatives of the UN and the IAEA are working out the specific details of the mission."

He said the mission would allow the resumption of full security at the plant.
