On Thursday, Biden announced an additional $800 million military aid package to Ukraine to boost its combat capability in the country's east.

He added on his Twitter account that the aid includes "heavy artillery weapons, dozens of howitzers, and 144,000 rounds of ammunition for them."

Recently, the US government sanctioned the Russian bitcoin miner, with the Office of Foreign Assets Control (OFAC) precisely placing Moscow-based Bittrefer on its blacklist. US authorities have added 10 Russia-based subsidiaries of Petriver AG, the Switzerland-based holding company of Petriver AG, to the list.

This is the first time that the United States of America has imposed sanctions on a cryptocurrency mining company. The latest sanctions aim to harm the Russian economy in the wake of Russian military operations on Ukrainian soil.

The Treasury also imposed sanctions on the Russian commercial bank Trans Capital Bank, whose representatives it said serve several banks in Asia, and suggested options to avoid international sanctions.

The measure freezes any US assets for those targeted and generally prevents Americans from doing business with them.
