Maltese police on Monday arrested eight suspects in the murder of blogger Daphne Caruana Galizia, Prime Minister Joseph Muscat said, almost two months after her car was blown up while she was driving it.

The joint security operation involved members of the police corps, armed forces and security services. Police now have 48 hours to interrogate the suspects and prosecute or release them.

All 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.

Daphne Caruana Galizia, 53, was killed in a car bombing near Mosta , Malta on 16 October. She ran a popular blog in which she relentlessly highlighted cases of alleged high-level corruption targeting politicians from across party lines.
