A suicide bomber blew himself up on Wednesday night in Yemen, injuring the security chief of the Yemeni province of Lahej and six other people, said residents and a security official.
Local sources said the security chief, Brigadier General Adel al Halemi, was in stable condition following the incident at the al Mindara district in the city of Aden.
The explosion happened outside of Halemi's home and could be heard from several kilometres away.
At least one security guard was in critical condition after the attack.
No one has yet claimed responsibility for the attack.
On Friday, seven people were killed and seven others wounded in a suicide car bomb attack in Yemen's southern city of Aden. DAESH terrorists claimed responsibility for the deadly attack.
Yemen has been mired in a conflict pitting the Shiite Houthi rebels against the country's internationally-backed government which is allied with a Saudi-led coalition. The fighting has killed more than 5,800 people since last March when the coalition began striking Houthi targets from air.
The chaos has allowed a powerful local Al Qaeda affiliate and a more recently formed branch of the DAESH terrorist group to expand their reach, including in Aden, Yemen's commercial hub.
