Iraqi hospital and police officials say a series of explosions across Baghdad have killed 35 people.

The blasts took place in at least seven neighborhoods across the city Tuesday evening and wounded dozens more.

Officials said about 80 people were injured by the bombings that mostly targeted Shiite neighborhoods.

The combination of car bombs and roadside bombs came just two days after gunmen in Baghdad held a Christian congregation hostage Sunday, in a siege that ended with 58 people dead.
