Iqbal Karim Bhuiyan not invited for taking oath as adviser to interim govt: CA Press Wing

A photo of an approval letter of the Cabinet Division circulating on Facebook claims that former army chief General Iqbal Karim Bhuiyan has been invited for taking oath as the adviser of the interim government, along with seven others.
The letter includes the name of Sheikh Abdur Rashid, secretary of the Cabinet Division, by order of the Chief Adviser. But, it does not have a signature.
However, the Chief Adviser's Press Wing confirmed that the picture of the letter is fake.
Chief Adviser's Press Secretary Shafiqul Alam posted the image on Facebook, labeling it as "fake and fabricated."
