The United States Department of Justice has announced charges against five alleged Russian intelligence agents accused of conspiring to carry out assassinations and attacks on behalf of the Kremlin, including within the United States. All five suspects remain at large.

The indictment, unsealed on Tuesday, identifies the defendants as Russian national Yuri Khrameev, 63, his son Kirill Khrameev, 27, Cuban nationals Oemis Romagoza Durruthy and Yaidel Delgado Suarez, both 35, and 22-year-old Venezuelan Angel Eduardo Castro.

All five face charges of conspiring to finance terrorism. Yuri Khrameev, Suarez and Castro face additional charges of conspiring to commit murder for hire.

Prosecutors said the group worked on behalf of Russian intelligence services to carry out attacks and killings internationally, including on US soil. The network allegedly recruited individuals in the United States to conduct surveillance on Russian dissidents, targeting people both domestically and in Lithuania.

At a news conference, Attorney General Todd Blanche said the plots included attempts to kill a Russian dissident believed to be living in the Washington, DC area.

In one instance, a recruit was allegedly promised $40,000 to make a US-based target "disappear." In a separate case from the previous year, another recruit was reportedly offered $25,000 to kill someone in Lithuania.

Russia's embassy in the United States has not commented on the case. Moscow has consistently denied accusations that it has orchestrated assassination operations on foreign soil.
