I reported this information to SO15 on 3 June 2017:

I found a share certificate for the Daesh-linked Tadhamon International Islamic Bank (see Forbes report below) that lists PO Box 5302, Taiz as a share holder’s business address. PO Box 5302 is the Headquarters of the privately owned $10-billion/annum HSA Group and also the address of YemPak - the al Qaeda front company I visited in 1997. Among numerous other entities and individuals, Qatar Islamic Bank is also listed on the share certificate.

PO Box 5302 is theYemPak factory address I visited in 1997 and that I now think was an al Qaeda logistics and operations centre. I believe that was where most of al Qaeda's attacks were planned and prepared for, including 9/11.

The Tadhamon International Islamic bank share certificate lists PO Box 5302 as the business address of HSA Group family member Mr. Ali Mohamad Saeed. The email address saeed95@hotmail.com is on an online business listing for YemPak, again found via google.

This Forbes.com article linked below lists Tadhamon bank as one of a few banks that continued to operate in areas under Daesh control in Yemen
