Spanish police release photos of six people suspected of planting a bomb that killed two police officers on the island of Mallorca

Spain remains on high alert following bomb attacks this week that left two dead and more than 60 wounded. Investigators have released photos of six suspected members of ETA who are wanted for questioning. They believe the people behind Thursday's bombings in Mallorca may still be on the island. Security has been stepped up ahead of the arrival of Spain's monarch Juan Carlos and his wife Sofia who traditionally spend their summer holiday there. On friday thousands took to the streets in Majorca to protest against terrorism. +++SYN-MAZ+++
