The Challenge: Identify Sudan note elements

Can anyone positively identify the following items that appear on some Sudanese banknotes? Precise names and locations of the buildings are appreciated, and links to supporting evidence is welcome, too.

1. The secretary bird at the center of this vignette appears on the front of B312 - B321. It is not the coat of arms of the country. Perhaps it is the logo of the bank?

2. Identified: Parliament House in Omdurman.

3. This building appears on the back of B342 - B344. Identified by Pavel Gusev: Ministry of Information and Communications in Khartoum.
