The International Mine Countermeasures Exercise (IMCMEX) is organised and led by Bahrain-based US Naval Forces Central Command, which is responsible for more than 2.5 million square miles of ocean.
"These participating nations are united by a common thread - the need to protect the free flow of commerce from a range of maritime threats including piracy, terrorism and mines," said Vice Adm. Kevin Donegan, commander, US Naval Forces Central Command in a statement.
"This region provides a strong training opportunity for nations worldwide as three of the six major maritime chokepoints in the world are here: the Suez Canal, the Strait of Bab Al Mandeb and the Strait of Hormuz," he said.
The exercise ends on April 26.
