A suicide car bomb killed seven people outside the Yemeni President's home in the southern city of Aden on Thursday.
A local official said a bomb blew up a security checkpoint about 500 meters from the Maashiq palace,injuring mostly civilians.
The officials said President Abd-Rabbu Mansour Hadi was inside the building at the time of the attack and was unharmed.
Hadi was forced to flee the capital Sanaa in 2014 and is now based in Aden, Yemen's second largest city.
His government is trying to reestablish its authority after Arab forces and loyalists seized the city in July.
