Twin bombings against a joint Sunni-Shiite prayer session at a mosque north of Baghdad on Friday killed 30 people and wounded 24 others, officials said, updating an earlier toll. The blasts at the Al-Salam mosque in Baquba, 60 kilometres (35 miles) from the capital, struck as worshippers were leaving following midday prayers, according to an army major and Ahmed al-Azzawi, a doctor at the city\'s main hospital.
