A suicide bomber attacked a Shiite mosque in Mosul City in northern Iraq on Friday, killing a worshiper and wounding three others, a local police source said.

"A suicide bomber wearing an explosive-belt blew himself up at the Shiite mosque of the al-Qubba in northwestern Mosul City, some 400 km north of Baghdad," the source told Xinhua.

The attacker could not enter the crowded mosque as militiamen guarding the mosque recognized him and shot him at the entrance, the source added.

In a separate incident, the source said that a police force raided a house in the Bab Sinjar neighborhood in western Mosul and freed two abducted people, including a 15-year-old girl.

The force also captured one of the kidnappers while the rest fled the scene, the source said.

Violence rages in Iraq as sectarian killings, suicide attacks, bombings, abductions cause dozens of Iraqi casualties daily.
