Al-Qaeda's growing presence in southern Yemen is raising fresh concerns ahead of the country's singe-candidate presidential election this week.
Last May, the city of Zinjibar fell to a group affiliated with al-Qaeda in the Arabian Peninsula.
A failed military offensive to push the group out of the city left massive destruction and triggered an exodus of refugees.
While remaining residents worry over the lack of security, it is said al-Qaeda is looking to expand its reach within the country.
