A senior commander of the Islamic Revolution Guards Corps (IRGC) said Saturday that US naval forces in the region are within an easy reach of the Iranian vessels, the semi-official Fars news agency reported.

The United States' huge and slow warships and aircraft carriers are proper hit-and-run targets for Iranian boats, Deputy Lieutenant Commander of the IRGC Ground Force for Operations, General Morteza Miriyan, told Fars on Saturday.

Iran enjoys the needed capability to have tough and serious confrontation against enemy threats at all levels and make them regret for their aggressive act, Miriyan was quoted as saying.

Western countries, including the United States and Israel, suspect the Iranian nuclear activities and claim that the Islamic republic is pushing its nuclear program for weapon-grade activities. Iran has stressed that its nuclear program aims at " peaceful" purposes.

The United States and Israel have not ruled out the possibility to attack Iran's nuclear facilities.

Also, Commander of Iran's Basij (volunteer) forces, Brigadier General Mohammad-Reza Naqdi, said Saturday that the weapons supplied by Western powers and their regional allies to the " terrorist" and dissident groups in the region will soon be used against the Zionist regime, Fars reported.

Naqdi described as "fruitless" the support extended by the United States, the West and the regional reactionary regimes to " terrorist" groups in Syria, and said the enemies should not feel happy about the companionship of a number of Syrian youth who have been deceived, because their hopes will fade away soon.

"The enemy should take a lesson from its continuous failures in Lebanon, Gaza, Egypt and the resistance in Syria and realize that sending weapons to break the line of resistance will yield no result but victory of the resistance front," Naqdi was quoted as saying.

UN-Arab League joint special envoy Kofi Annan on Saturday urged world and regional powers to unite in order to find a solution to the Syria crisis as ministers started a close-door meeting in Geneva.

Annan said in his opening remarks at the Action Group on Syria meeting that relevant countries have to make a clear choice between "either unite to secure your common interests; or divide, and surely fail each in your own individual way" as "an international crisis of grave severity now looms."

He warned of the extreme dangers posed by the conflict to Syrians, to the region and to the world.
