Two held in shipwreck tragedy that killed 900

Greece picks up more than 120 migrants from three ships in new rescue operation in Aegean

Italian police on Tuesday arrested the captain and first mate of a boat involved in the Mediterranean's deadliest disaster in decades on suspicion of murder, causing a shipwreck and involvement in illegal immigration.

The two seamen, who have not been formally charged, were being held as part of a probe into a catastrophe that has evoked chilling comparisons with the slave trade and allegations of callous disregard on the part of European governments.
