LITTLE ROCK, Ark. (AP) - The Arkansas attorney general asking a judge to reject an effort by eight inmates facing execution next month during a 10-day period to prevent the state from putting them to death.

Attorney General Leslie Rutledge's office says it asked a Pulaski County judge Thursday to dismiss the complaint by the inmates challenging Arkansas' lethal injection law and its three-drug protocol as unconstitutional. Governor Asa Hutchinson has scheduled four double executions for the eight men beginning April 17.

Rutledge's office called the amended complaint an effort to "artificially prolong" a case that ended when the state Supreme Court upheld Arkansas' lethal injection law.

The Arkansas Supreme Court earlier Thursday rejected a separate attempt by one of the inmates to block his execution next month.
