The state has rescheduled executions for seven death row inmates as it tries to find new lethal drugs, meaning no inmate will be put to death in Ohio in 2015.

The announcement Friday affects six executions this year, including one set for Feb. 11, and one previously scheduled for 2016 that was pushed farther back.

The state prisons agency said the move follows a federal judge's previous order delaying executions while the state puts a new execution policy in place.

That policy calls for Ohio to use drugs it doesn't have and has had difficulty obtaining in the past.

The delays mean that for the first time Ohio won't execute anyone in a calendar year since the state resumed putting inmates to death in 1999.
