Five Yemeni detainees at the U.S. Guantanamo Bay in Cuba are expected to appear in a U.S. court in this summer.

They include Ramzi Al-Shaibah, Walid Bin Atash and Abdul Rahim Al-Nasheri.

The five had previously been tried by military commissions in the U.S. that were already canceled.

Weeks ago, the U.S. released a Yemeni Gitmo detainee and sent him to Spain. The release took place, according to the U.S. officials, after Yasin was found cooperative with the authorities.

Meanwhile, Abdul Salam Al-Hila, another Yemeni detainee, has told his family that he faced a new assassination attempt at the U.S. Bay which the U.S. President Obama ordered to be closed as soon as possible.

His brother said that they received a letter from Abdul Salam telling them he had faced a new assassination plot arranged by the jail officials.

Last year Al-Hila revealed an assassination plot he had faced at the jail.

Separately, the release of the rest Yemeni detainees at Gitmo, who account for almost half of the remaining detainees, is still controversial as the U.S. wants to send them to a third country to rehabilitate them amid fears the national rehabilitation programs

and centers can't ensure they would not regroup.

But Yemen insists on sending its people to their homeland, assuring that it would do its best to ensure they would be well rehabilitated and reintegrated into the society.

The U.S. has already released some Yemeni detainees but it refuse to release the others, after it found out that those who were released were back to terrorist groups posing threats to the U.S. national security and economic interests.
