Workers at the Aden port have been threatened to be killed and fired from their jobs after they refused to accept a bribe in return for keeping silent over the arms cargo which was seized on Saturday, Alahale website reported.

Three workers at the port received telephone calls from unknown numbers and were threatened to get shameful fate, the website quoted a statement by local sources.

"A minister from the power-sharing government has arrived in Aden and is searching for a legal document to bury the topic of the Turkish-made pistols cargo," it quoted the statement, that was posted on the Bandar Aden website.

Earlier today, a Yemeni official said the pistols were shipped inside biscuit boxes for a domestic trader with the name of Rashid Al-Badani.

Furthermore, Alahale quoted local sources as saying the cargo included more than 3000 pistols worth $120 million that were imported from a special Turkish company.

The seizure was almost the second in the past few months after the Iranian products that were shipped to the country to reassemble them and produce weapons including missiles.

Iran has been accused of providing financial, military and technical assistance to the Shiite Houthi Group in Saada on the border with Saudi Arabia.

Maritime piracy off the Gulf of Aden and Somalia, which has recently soared, boosts the danger of weapons smuggling to Yemen which has been struggling to cope with big challenges including security disorder that were deepened by the unrest.
