Friday’s bomb attack came a day after another blast (pictured) near the presidential palace housing the president and prime minister

A suicide bombing killed seven people and wounded seven others Friday night in Aden, the second deadly attack in as many days in Yemen’s second city, medics and security sources said.

The bombing targeted a police checkpoint not far from Thursday’s suicide attack that killed eight people, including soldiers and civilians, outside the presidential palace in the city, the sources said.

A hospital spokesman confirmed that seven people were killed in Friday’s bombing.

There was no immediate claim of responsibility for the attack but the ISIS militant group said it was responsible for Thursday’s bombing.

Al-Qaeda and the rival ISIS group both have a presence in Aden, where militants occupy government buildings and are seen patrolling several districts and intimidating civilians.

They have claimed a string of attacks and assassinations in recent months.

President Abedrabbo Mansour Hadi was in the palace at the time of Thursday’s attack but unharmed, a government official said.

Aden has become the temporary headquarters of Hadi’s government as it battles to retake large parts of Yemen from Houthi militias.

Hadi fled to Aden after escaping house arrest in the capital Sanaa, which was overran by the Houthis in September 2014.

The rebels then moved south forcing Hadi to flee in March to Riyadh.

But Hadi loyalists backed by Saudi-led air strikes recaptured the port city of Aden but they are still battling to retake other provinces and push toward the Houthi-held capital.
