Lawyers and relatives of four Salvadoran military officers sought by Spanish courts for trial on their alleged role in the killing of six Jesuit priests say El Salvador's Supreme Court has rejected the foreign court's petition.

Defense attorney Lisandro Quintanilla said Tuesday in a local radio interview that the Supreme Court decided in favor of his clients.

The Spanish court seeks the extradition of 17 ex-military officers, but the Supreme Court's decision applies only to four who are in custody. They were accused of involvement in the 1989 killing of six priests, five of whom were Spanish, and two of their employees.

The killings occurred during El Salvador's civil war.

The lawyers say they have not been notified officially. The court's communication office says it doesn't have official information yet.
