A suicide bombing killed seven people and wounded seven others on 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 Islamic State militant group said it was responsible for Thursday’s bombing.
Al Qaeda and the rival IS group both have a presence in Aden, where Islamist 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 Abd-Rabbu 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 Shia Houthi rebels.
Hadi fled to Aden after escaping house arrest in the capital Sanaa, which was overrun by the Houthis in September 2014.
The rebels then moved south forcing Hadi to flee in March to Riyadh.
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 rebel-held capital.
The United Nations says more than 5,800 people have been killed in the impoverished country, about half of them civilians, since the coalition air campaign was launched 10 months ago.
l Houthi gunmen detained a local journalist and five activists after a raid on an apartment in Sanaa yesterday, activists said, the latest detention of a  reporter in the country.
The gunmen stormed the apartment at dawn and took journalist Nabil al-Sharabi and the activists to an unknown location. The Houthis had fired guns when the men attempted to escape, activists said.
Human Rights Watch says the Houthis have detained numerous political opposition figures, activists, and journalists.
Sharabi, the detained journalist, had worked for local daily Akhbar Al Youm, which the Houthis closed down after taking control of Sanaa in 2014.
