WASHINGTON (Reuters) - The United States on Tuesday condemned the slaying of Maltese journalist Daphne Caruana Galizia and said the FBI had responded to Malta s request for assistance in investigating the car bomb attack that killed her. State Department spokeswoman Heather Nauert said the United States condemned the  appalling violence that took place against her in the strongest terms,  calling it a  cowardly attack  against a reporter who was dedicated to fighting corruption.  We responded quickly to the prime minister s request for assistance. The government of Malta and Malta police force have been in contact with the FBI about the investigation and the FBI is providing specific assistance,  said Nauert, who called for a  thorough, transparent and independent  probe.
