CAIRO (Reuters) - A bomb exploded at a Shi'ite Houthi mosque in the Yemeni capital Sanaa on Friday, wounding 13 people, a security source said, and the Islamic State claimed responsibility for the attack in a statement on Twitter.
The bombing came against a backdrop of civil war in the country. Iranian-backed Houthi rebels have seized large swathes of territory, including Sanaa, prompting formation of a Saudi-backed Arab coalition that is using air power to try to halt their advances. Sunni Islamist militants have been seeking to extend their influence amid the chaos.
