A government spokesman says the president of the Maldives has fired his defense minister in what is believed to be part of an overhaul after an explosion on his speedboat last month which officials suspect was an assassination attempt.

President Yameen Abdul Gayoom has removed Defense Minister Moosa Ali Jaleel from his post, the presidential spokesman said in a tweet.

He did not give a reason but Jaleel's firing comes amid arrests and transfers in the defense minister that followed the Sept. 28 blast that wounded Gayoom's wife, an official and a bodyguard.

The explosion happened when Gayoom and his wife were returning by boat from the country's airport to the capital. They are on separate islands in the archipelago state.

Two soldiers have been arrested.
