 Oman's state-owned media say the attack targeted worshippers at a Shia prayer hall in the capital, Muscat, Monday night during the annual Ashura commemoration. In addition to those killed, dozens were wounded, many of them migrant workers from Pakistan. Police in Oman say an investigation is ongoing into the incident. Pakistan's foreign ministry condemned it as a terrorist attack and the Pakistani ambassador there visited a hospital where many of the wounded were being treated.
