Salvadoran police say they've arrested four former soldiers wanted in Spain for the 1989 murder of six Jesuit priests in the Central American country. Five of the priests were Spanish.

The national police force says in a Twitter post that the four were arrested at the behest of Interpol.

They are named as Col. Guillermo Alfredo Benavides Moreno and soldiers Antonio Ramiro Avalos Vargas, Angel Perez Vasquez and Tomas Zarpate Castillo.

It's up to El Salvador's Supreme Court to rule on the extraditions.

The killing was among the most notorious incidents of El Salvador's civil war. Military authorities apparently saw the priests as leftist sympathizers.

On Friday, a U.S. judge cleared the way for another former Salvadoran colonel to be extradited to face charges in Spain in the case.
