In a two-pronged action, the Treasury and Commerce Departments announced the punishments as part of Washington's continued response to the overthrow of Nobel laureate Aung San Suu Kyi's elected government.

Secretary of State Antony Blinken said in a statement that the new sanctions were levied "in response to the brutal campaign of violence perpetrated by the Burmese military regime and to continue imposing costs in connection with the military coup."

The sanctions do not target the Myanmar people, but are aimed at pressuring the military to "immediately restore Burma's path to democracy," Blinken said.

The sanctions target Myanmar's minister of information Chit Naing, minister for investment Aung Naing Oo, labor and immigration minister Myint Kyaing, and Thet Thet Khine, the minister for social welfare, relief and resettlement.

Three members of the powerful State Administrative Council were also hit with sanctions, as were 15 spouses and adult children of officials, in an expansion of US punishments imposed in February, March and May following the coup.

Under the sanctions, all US property in the name of the individuals are blocked, and Americans or people in the United States are prohibited from conducting property or interest transactions with them.

Andrea Gacki, director of Treasury's Office of Foreign Assets Control, said in a statement the action demonstrates Washington "will continue to impose increasing costs on Burma's military and promote accountability for those responsible for the military coup and ongoing violence."

The Commerce Department meanwhile slapped sanctions on four business entities: King Royal Technologies Co., which provides satellite communications services supporting the military; and Wanbao Mining and its two subsidiaries, which have revenue-sharing agreements with a company that helps fund the country's defense ministry.

The actions come as Myanmar rejected new figures released by the United Nations, which said there were reports from within the country that security forces have killed at least 883 unarmed people, including at least 40 who are believed to have died in custody.

At a Tuesday briefing, a spokesman for UN Secretary General Antonio Guterres told reporters that the global agency's country team also determined that 5,202 people were in detention as a result of their opposition to the military takeover.

Myanmar's Ministry of Foreign Affairs "strongly objects" to the numbers presented by the United Nations, spokesperson Nay Pyi Taw said in a statement.

"The United Nations is requested not to release one-sided remarks without verification and to verify sensitive information with relevant focal ministries before its release," the spokesperson added.

Authorities Wednesday released more than 2,000 anti-coup protesters from prisons across Myanmar, including local journalists jailed after reporting critically on the junta's crackdown.
