The mayor of Kyiv has reported multiple explosions in the Ukrainian capital for the first time in weeks.
Vitali Klitschko wrote in a post on Telegram that there were explosions in a central district of the capital that is home to many government agencies and buildings.
He said municipal teams were in place and more details were expected.
The reported blasts come as Ukraine has faced a barrage of Russian air strikes across the country, largely targeting infrastructure, in recent weeks as well as continued fighting along the front lines in the eastern and southern regions.
It was not immediately clear what the targets were, or whether civilian, administrative, or military sites were the aim.
On Tuesday, US officials said the United States was poised to approve sending a Patriot missile battery to Ukraine, agreeing to an urgent request from Ukrainian leaders desperate for more robust weapons to shoot down incoming Russian missiles.
Ukrainian President Volodymyr Zelensky pressed Western leaders as recently as Monday to provide more advanced weapons to help his country in its war with Russia.
The Patriot would be the most advanced surface-to-air missile system the West has provided to Ukraine to help repel Russian aerial attacks in the war between the countries that erupted with Russia's invasion of Ukraine on February 24.
