The Department of Justice has filed charges against a Pakistani man who allegedly has ties to Iran with planning to hire hit men to carry out the assassination of unidentified U.S. government officials.

Asif Raza Merchant, 46, who is accused of trying to arrange a murder-for-hire scheme, was arrested on July 12, though the complaint was not unsealed until Tuesday. According to the FBI, his scheme is believed to be tied to Iran’s repeated and public vow to get revenge against Trump administration officials who were involved with the January 2020 assassination of Iranian military leader Gen. Qassem Soleimani.
