At least 21 people were killed and 74 injured in a bomb blast outside a mosque in Tikrit, in Iraq on Friday. It was followed by a suicide attack against a hospital where victims were being treated. The dead included two members of Salaheddin provincial council. Doctors at the hospital said they have received 19 dead bodies and treated 72 injured persons. The bomb was hidden inside a fuel canister at the entrance to the mosque, where provincial officials often attend prayers. A subsequent suicide attack inside the hospital where the victims were being treated killed two people and wounded two others, a security official in Tikrit said. The attacks came a day after a spate of coordinated bombings in west Iraq killing 10 people.
