Iranian warship the Jamaran on Sunday test-fired a home-built torpedo for the first time as part of ongoing naval war games in the Gulf, state television's website reported.

"This torpedo is anti-submarine and when it is fired from the warship, it automatically hunts for the submarine and destroys it," navy commander Arya Hassani was quoted as saying.

Iran positive on fresh nuclear talks with West: media
Ankara (AFP) May 8, 2010 - Iranian Foreign Minister Manouchehr Mottaki has welcomed a proposal for new talks with Western powers over his country's nuclear programme, possibly in Turkey, media reported late Friday.

"This idea has been accepted by Iran. If we agree on a date, this meeting may be held in a short time," Anatolia news agency quoted Mottaki as saying after talks with the Turkish foreign minister in Istanbul Friday evening.

"The venue of the meeting will be very probably Turkey. This proposal is a good proposal for us," he said.

Turkish Foreign Minister Ahmet Davutoglu said he had proposed the meeting in Turkey during his visit to Tehran last month.

He had suggested talks between Iran's top nuclear negotiator Saeed Jalili and EU foreign policy chief Catherine Ashton, as a representative of powers in the so-called P5+1 group working on the Iran nuclear standoff.

"We have offered a meeting with P5+1 in Turkey. Iran is positive on this proposal. A reply is being awaited from Ashton," he said.

"The resumption of talks between the P5+1 and Iran is a must. The way for diplomatic efforts should be opened," he said.

The P5+1 group consists of permanent UN Security Council members Britain, China, France, Russia and the United States, plus Germany.

Turkey and Brazil, both non-permanent members of the Security Council opposed to fresh sanctions against Iran, have recently stepped up efforts for a diplomatic solution of tensions over the Islamic republic's nuclear activities.

World powers and Iran have been at loggerheads for months over a proposed deal to supply nuclear fuel for a Tehran research reactor in exchange for low-enriched uranium from Iran.

The deal stalled after Iran insisted the two materials be exchanged simultaneously within its borders. That was rejected by the world powers, who accuse Iran of masking a weapons drive under the guise of what Tehran says is a purely civilian atomic programme.

The United States has been spearheading a drive for a fourth round of UN Security Council sanctions against Iran.

The report said the torpedo was fired from the Iran-built Jamaran, which was deployed earlier this year. It has a displacement of around 1,400 tonnes and is equipped for electronic warfare.

On Wednesday the Islamic republic's navy began eight days of manoeuvres in the Gulf, Sea of Oman and the northern Indian Ocean covering an area of 250,000 square kilometres (around 97,000 square miles).

The drill comes weeks after a similar exercise by the elite Revolutionary Guards Corps in the Gulf and in the key oil route of Strait of Hormuz.

Iran's armed forces regularly conduct such drills, often test-firing what they say are home-built missiles.
