Is it a confirmed news (any sources??) or just something that was said on a forum?
Its not confirmed in a sense that no official discussion over the issue has taken place. The BD Defence Sctry just said to PM that they were interested in jf-17 and various sources (experts and officials) in Pakistan say they were interested in 12 early models. Since this was not revealed in a press conference by GOP or GOB, it did not make it in the newspapers. Howeverm it is well known thing around here that BD is interested in 12 jf-17s at this moment.
bangladesh just ordered/received some F-7Gs from China. I do see FC-1 flying in bangladesh airforce but it might take few years.
For BAF, an F-7 is like F-16. They call it poor people's F-16. I also see them with JF-17. It serves Pakistani and Chinese strategic interests as well.
