*ISLAMABAD - Hassan Nawaz and Hussain Nawaz names have been placed on the blacklist. T*he names have been placed on the blacklist by the Immigration and Passport Directorate on the request of the National Accountability Bureau (NAB).
Sources said both the sons of former prime minister Nawaz Sharif would no longer be able to use their Pakistani passports as their travel documents have been blocked.
Last year, a accountability court had declared them proclaimed offenders in three NAB references.
The NAB had filed four references in the accountability court against former prime minister Nawaz Sharif, his two sons -- Hussain Nawaz and Hassan Nawaz -- his daughter Maryam Nawaz, son-in-law Captain (retd) Muhammad Safdar and Finance Minister Senator Ishaq Dar.
