Members of the US House of Representatives have asked the White House to investigate how US weapons reach al Qaeda in Yemen through the UAE and Saudi Arabia.

Members of the House Foreign Affairs Committee called on President Donald Trump, Foreign Secretary Mike Pompeo and Acting Defense Minister Patrick Chanahan to explain how US military equipment sold to the UAE and Saudi Arabia has been transferred to al Qaeda in Yemen.

They expressed deep concern over reports accusing Saudi Arabia and the UAE of transferring these weapons to extremist groups.

"According to the bilateral agreements to sell these weapons to Saudi Arabia and the UAE, the two countries are prohibited from transferring these weapons to a third party," Al Jazeera correspondent in Washington said.

According to the reporter, the situation is worse when the third party is a "terrorist party" according to the American classification, and even that the US forces have been carrying out attacks against these groups in Yemen.

If Congress confirms that the government or the Pentagon are not doing the required investigation, it will have to open its own investigation to highlight the elements of this thorny issue, says Waqfi.

The US station "CNN" revealed in an investigation of the presence of large numbers of US armored vehicles in areas under the control of the Huthis and the other controlled by al-Qaeda in Yemen.

The investigation pointed out that Saudi Arabia and the United Arab Emirates used American weapons to buy the loyalty of the militias or Yemeni tribes.

The investigation added that an official in the US Department of Defense requested an investigation into the leaking of US and Yemeni weapons by Yemen and Saudi Arabia.
