An investigation by Al-Jazeera revealed the details of the two assassinations and secret prisons in Aden, Yemen, through investigation records and exclusive testimonies.

According to the investigation, titled "Death Belts", the minutes of the investigation confirmed that the head of the assassination gang in Aden was working with the Emiratis, especially with "Abu Khalifa."

According to the minutes of the investigation obtained by the island that elements of al-Qaeda carried out assassinations under the guidance of Emirati officers.

Between 2015 and 2019, southern Yemen has seen more than 100 assassinations, according to UN reports.

Most of the assassinations or attempts to assassinate imams in Aden were carried out by people driving motorcycles, while others were carried out by roadside bombs. The operations were highly professional.

These operations have not been properly investigated by the security forces, and no gunmen have been brought to justice, and reports have always referred to them as unidentified gunmen.
