"The UAE has recently transferred an ISIL commander namely Abu Bakr al-Zokhri (with Sudanese nationality), nom de guerre Khaibar al-Sumali, from Iraq to Aden in Yemen to recruit and strengthen the ISIL in Yemen," Ali Abdullah al-Bujairi said in an interview with Qatar's Arabic-language al-Sharq newspaper on Monday.
He added that the UAE is now organizing the ISIL in Southern Yemen and supporting al-Qaeda in the country under the pretext of fighting against them.
An investigation by the Associated Press last August found a military coalition battling Ansarullah forces' secured secret deals with al-Qaeda in Yemen and recruited hundreds of the group's fighters.
It added that the coalition had been paying some al-Qaeda commanders to leave key cities and towns while letting others retreat with weapons, equipment and wads of looted cash.
For more than two years, a Saudi-led alliance - backed by US logistical and weapons support - claimed it crushed al-Qaeda's ability to carry out attacks from Yemen.
Hundreds of al-Qaeda members were recruited to join the coalition as soldiers, the report said.
