Original story:

At least 15 people were killed Thursday after a large explosions triggered by two suicide bombers rocked a mosque in Yemen's rebel-held capital, according to media reports. The attack reportedly took place at the Al Bilaili mosque in Sanaa during prayers for the Muslim holiday of Eid al-Adha, which marks the end of hajj.

Officials said that the death toll could rise as several people were seriously injured, CNN reported, adding that at least 29 people have been killed. However, this number could not be confirmed.

No group has so far claimed responsibility for the attack on the mosque, located near a police academy in Sanaa, which is controlled by Houthis, a Shiite group that took over the capital last year. The Yemeni capital has witnessed a series of bomb attacks over the past few months, many of which have been reportedly claimed by the Islamic State group, which is Sunni.

The attack comes two days after Yemen's President Abdrabbuh Mansour Hadi returned to the city of Aden from exile in Saudi Arabia. He had fled in March after Houthi rebels gained prominence in the country. Houthi rebels have since been targeted by a Saudi-led coalition that has pushed them back from some areas, including Aden. But the group still remains in control of Sanaa.
