The prosecutor's office at Spain's National Court has asked the tribunal not to issue an international arrest warrant for three US soldiers whose tank fired on a Baghdad hotel during the Iraq war, killing a Spanish journalist and one other, a court official said. Prosecutor Pedro Rubira said in his appeal: "Spain lacks jurisdiction to investigate causes of death in a military conflict and death of a Spanish citizen resulting from US military gunfire."Rubira also said in his appeal that the three men have not been indicted, as the case is still in an early phase, the court official said on Thursday on customary condition of anonymity.
