Turkey's Foreign Affairs Ministry on Thursday condemned the suicide bombing during prayers at a mosque in Yemen's Sanaa for the Eid al-Adha holiday on the same day. Killing 25 people, the attack was later owned by the terrorist group ISIS.

"We strongly condemn the suicide bomb attack on Sanaa's Belili Mosque, which was carried out during Eid-al Adha prayers and which claimed numerous lives," the ministry declared in a statement.

Turkey, it went on, "reiterates its support for efforts to establish a legitimate government in Yemen and the efforts made by the brotherly people of Yemen to establish peace, security and stability in the country."

The ministry added: "We wish for God's mercy on those who lost their lives [in Thursday's attack], convey our condolences to the families of those slain, and wish the injured a speedy recovery."

Responsibility for the attack, which killed at least 25 people and left dozens injured, was claimed by the Daesh-affiliated Wilayet Sanaa group.

On Thursday morning, a car bomb went off outside the mosque, which was packed at the time with Shia worshippers performing Eid al-Adha prayers, according to eyewitnesses.

Yemen descended into chaos last September, when the Shia Houthi militia overran Sanaa.

In April, the Houthis also captured Yemen's southern Aden province, prompting President Abd Rabbuh Mansour Hadi - along with most of his government-to flee to Saudi Arabia.

For the last six months, Saudi Arabia and its Arab allies have carried out a wide-ranging air campaign targeting Houthi positions across Yemen, which recently allowed pro-Hadi forces to retake most of Aden province.

Earlier this week, Hadi finally returned to Aden-where he held a cabinet meeting on Wednesday-after five months in Saudi Arabia.
