(Reuters: Darrin Zammit Lupi, file) Maltese police have arrested eight suspects in the murder of journalist Daphne Caruana Galizia, Prime Minister Joseph Muscat said, almost two months after her car was blown up while she was driving it. All of the suspects are Maltese nationals and most have a criminal record, the Prime Minister said, without providing any further details. The police have 48 hours to question the suspects, arraign them or release them. Galizia, 53, was murdered on October 16. She ran a popular blog in which she relentlessly highlighted cases of alleged high-level corruption, targeting politicians from across party lines. She died in the blast that wrecked her car as she was leaving her house, throwing debris and body parts into a nearby field. The murder shocked the Mediterranean island, the smallest nation in the European Union, and Mr Muscat promised a reward to anyone who came forward with information about the killing. Galizia had used her widely read blog to lambast Mr Muscat, his wife and some of his closest advisers, accusing them of setting up off-shore accounts to hide ill-gotten gain. They denied the charges and Mr Muscat was suing Galizia for libel at the time of her death. In October, a local police source said investigators believed powerful Semtex explosives might have been used in the killing, adding that if proven, it would be a first for Malta.
