The US Supreme Court has approved some of the first executions of federal prisoners in 17 years.
These were previously delayed after a judge ruled that there were still unresolved legal challenges in the justice department.
Among those is Daniel Lewis Lee, who was convicted of torturing and killing a family in Arkansas in 1996.
He was due to be executed on Monday.
The Supreme Court voted 5-4, confirming that executions may proceed as planned.
