New York:  The long arm of US law enforcement reached around the world to seize four men accused of "narco-terrorism" conspiracies to help Hezbollah and the Taliban, officials said on Tuesday.

Two men were captured in the Indian Ocean island nation of the Maldives and another two in Bucharest, the Romanian capital, and were being brought before a Federal Judge in New York, Manhattan US Attorney Preet Bharara said in a statement.

Three of the four were accused of conspiring to support Hezbollah, the Lebanese political party and military organization, which Washington designates a terrorist group.

According to the indictment undercover US narcotics agents pretending to represent Hezbollah agreed to purchase hundreds of kilograms of heroin.

The agents then struck a deal in February to sell the alleged gang "military-grade weaponry" destined for Hezbollah.

The USD 9.5 million weapons package discussed included surface-to-air missiles, Russian and US-made assault rifles, sniper rifles and ammunition. A down payment of USD 100,000 was transferred for the weapons.

Separately, a man was arrested the Maldives and extradited to New York on charges that he sold heroin he believed was destined for the United States and sold assault rifles he thought were going to the Taliban guerrilla movement fighting US forces in Afghanistan.
