U.S. admiral urges Iran Guard navy to communicate

DUBAI (Reuters) - The U.S. chief of naval operations on Thursday urged the navy of the Iranian Revolutionary Guard to communicate better with other vessels to avoid incidents in the Gulf.

"The behavior of the Guard navy is not very professional and not very supportive of peace in the Gulf area," Admiral Gary Roughead said at a news conference in Dubai.

In January, the United States said Iranian boats aggressively approached three U.S. naval ships and warned they would explode. Iran said it was a routine contact.

"I would like to see the Iranian Revolutionary Guard navy ... more mindful of the importance of communicating not just with the U.S. Navy but with any other navy about intentions and movements," Roughead said.

Tension has been high between Washington and Iran in Gulf waters, which are vital to world oil shipments.

Relations were already tense over Iran's nuclear program, which the Islamic Republic says is peaceful but the United States suspects is aimed at developing atomic weapons.

Another incident occurred this month, when three boats approached a U.S. Navy patrol vessel at high speed, stopping only after it fired a flare.

The Bahrain-based U.S. Fifth Fleet said at the time that the American vessel had tried to communicate with the boats by routine methods but decided to fire a flare after receiving no response.

The Iranian Revolutionary Guard, labeled by the U.S. Senate a terrorist organization, patrols Gulf waters.
