Iraq worshippers killed in mosque blast

A suicide bomber has blown himself up inside a Shia mosque in the Iraqi capital, killing at least seven worshippers, police said.

More than 20 people were wounded in Tuesday's attack in the al-Qahira district of northern Baghdad.

"The suicide bomber detonated himself among the worshippers, who were gathering after the call to prayer," said policeman Furat Faleh, who was near the site of the blast.

More than 70 killed in wave of Baghdad bombings

More than 70 people were killed in a wave of bombings in markets in Shi'ite neighborhoods across Baghdad on Monday in worsening sectarian violence in Iraq.

No group claimed responsibility for the blasts. But Sunni Muslim Islamist insurgents and al-Qaeda' s Iraqi wing have increased attacks since the beginning of the year and often target Shi'ite districts.
