The journalist who led the Panama Papers investigation into corruption in Malta was killed on Monday in a car bomb near her home, The Guardian reported.

Daphne Caruana Galizia died on Monday afternoon when her car, a Peugeot 108, was destroyed by a powerful explosive device which blew the car into several pieces and threw the debris into a nearby field.

A blogger whose posts often attracted more readers than the combined circulation of the country’s newspapers, Galizia was recently described by the Politico website as a "one-woman WikiLeaks". Her blogs were a thorn in the side of both the establishment and underworld figures that hold sway in Europe’s smallest member state. 

Her most recent revelations pointed the finger at Malta’s prime minister, Joseph Muscat, and two of his closest aides, connecting offshore companies linked to the three men with the sale of Maltese passports and payments from the government of Azerbaijan.

No group or individual has come forward to claim responsibility for the attack.

Malta’s president, Marie-Louise Coleiro Preca, called for calm. "In these moments, when the country is shocked by such a vicious attack, I call on everyone to measure their words, to not pass judgment and to show solidarity," she said.
