Twin bomb attacks claimed by ISIL terrorists killed at least 29 people in a mosque during Eid al-Adha prayers on Thursday in the Yemeni capital of Sana’a.

According to the Yemeni al-Masirah TV network, two terrorists blew themselves up at the al-Balili Mosque in al-Safia neighborhood in Sana’a, leaving the 29 worshipers dead and many others injured.

Reports said that the assailants managed to enter the mosque wearing women’s clothes.

The terrorist attack came as Muslims around the world marked Eid al-Adha, the Feast of the Sacrifice, the most important holiday of the Islamic calendar.

Witnesses said that after a first blast inside the mosque, a suicide bomber detonated an explosives belt at the entrance as worshippers rushed outside.

The perpetrators hid explosives inside shoes and clothing to get past body searches introduced at the entrance after the other attacks, according to the mosque's head of security, Adnane Khaled.

"We found a shoe bomb and explosives hidden in underwear and abandoned in the toilet," he said, adding that two devices had failed to detonate while a third had exploded inside the shrine, causing panic.

"As the crowd rushed to leave the prayer room, a suicide bomber tried to force his way into the mosque," said Khaled. "He was stopped at the entrance by a security officer and blew himself up."
