An explosion on a speedboat carrying Maldives President Abudullah Yameen was an assassination attempt, the minister at his office told Reuters on Tuesday, citing the findings of international investigators including a team of Sri Lankans investigators.

Two military officials have been arrested, the Minister, Mohamed Hussain Shareef, added.

Yameen was unhurt in the Sept. 28 blast on board in presidential launch as it approached the capital Male, but his wife and two aides were injured. Initially the government said it could be due to mechanical failure.

A Sri Lankan team left for Maldives on October 1 and returned early this week after their investigation.
