MALE: The Maldives government insisted Sunday its president had survived an assassination attempt on his boat even though the FBI found no evidence of a bomb blast that led to the arrest of his deputy.

The US Federal Bureau of Investigation (FBI) however said it has found no conclusive evidence that an explosion on a boat transporting Maldives President Abdulla Yameen was caused by a bomb. Yet, the Maldives government said the FBI statement was contrary to the outcome of other investigators.

Though the government initially said the blast on Sept. 28 could have resulted from mechanical failure, it later cited investigators from the FBI, Australia, Saudi Arabia, India and Sri Lanka to assert it was an attempt on Yameen’s life.

President Yameen was unharmed in an explosion on his speedboat on Sept. 28 that slightly injured his wife and was described by authorities as an attempt on the leader’s life.

Police arrested Vice President Ahmed Adeeb almost a month later for treason, fuelling fears of fresh political turmoil in the honeymoon islands after a series of sackings of senior government officials.

The FBI was one of the outside agencies asked by the government to look into the blast.

Josh Campbell, an FBI spokesman, said in a statement emailed to Reuters on Saturday that the evidence submitted for analysis was determined to be from the boat and not parts of an improvised explosive device (IED).

Home Minister Umar Naseer said he had received a report from the FBI, which found no evidence that a bomb caused the explosion.

But Naseer described the US agency’s report as “inconclusive,” adding that Saudi Arabian and Sri Lankan investigators had confirmed the likelihood of a bomb.
