At least 25 people are reported dead and dozens more injured in a suicide attack at a mosque in the capital of Yemen where worshippers were celebrating the Muslim Eid al-Adha holiday on Thursday.

There was no immediate claim of responsibility for the bloodshed at the mosque in Sanaa, run by the Shi’ite Houthi group – but it resembles previous bombings by Sunni Muslim ISIL militants.

They have exploited the conflict between the Iranian-allied Houthis who seized Sanaa a year ago and a Saudi-led Arab coalition waging airstrikes to evict the Houthis.

Many civilians have also died in the airstrikes which have helped the coalition secure enough territory for Yemen’s exiled President Abd-Rabbu Mansour Hadi to return to the southern city of Aden on Tuesday.

The UN children’s agency, UNICEF, says the conflict has forced more than 1.3 million people to flee their homes.
