A senior southern leader, Mohammad Ali Ahmed, survived on Monday an assassination attempt in Al-Mukla city of Hadhramout governorate.
An explosive was detonated at the vehicle of Ahmed while he was outside his car in Hadhramout.
Ahmed is considered among the prominent southern leaders, and he spent about 18 years in exile.
He stated after his return home early of the current year that he came back to struggle for the sake of the southern independence.
Yemeni officials including Deputy Chairman of the Political Security Nasser Hadi, the former Interior Minister Hussein Arab, Deputy Governor of Aden Hassan Al-Darab and other officials welcomed Ahmed in Aden Airport.
Ahmed served as a governor of Abyan, and as interior minister before the Yemeni unification in 1990.
No side claimed responsibility for the assassination attempt, but some southern leaders accuse Ali Salem Al-Beidh of standing behind the bombing.
