BAGHDAD — Seven people were killed in Baghdad and in the western city of Fallujah yesterday, including a mosque preacher who was gunned down outside a candy store, Iraqi officials said.

A police officer said assailants shot dead the preacher, Sheik Talib Zuwayid of the al-Baraa mosque in Fallujah, along with his nephew and another man.

Residents said Zuwayid was one of the organizers of weekly Sunni demonstrations against the Shiite-led government over the past three months.

In the Iraqi capital, two separate explosions killed four people and wounded 14. Militants seeking to undermine the Iraqi government are suspected.
