Attacks killed five people in Iraq on Tuesday, officials said, the latest in a surge in violence that security forces have failed to curb despite launching major operations targeting militants.

Bombings killed a soldier, a Sahwa anti-Al-Qaeda fighter and a civilian in Salaheddin province, north of the capital, while gunmen shot dead a former soldier and a civilian in the northern province of Nineveh, according to security and medical officials.

The attacks came a day after bombs targeting a cafe, a football field and a market in areas north of Baghdad killed 24 people.

Authorities have repeatedly highlighted recent security operations -- among the largest since US forces departed in December 2011 -- which they say have led to the killing or capture of many militants.

But whatever gains the operations have made, they have failed to stop the bloodshed.

Violence in Iraq has increased markedly this year, with analysts saying the upsurge is driven by anger among the Sunni Arab minority that the Shiite-led government has failed to address, despite months of protests.

Attacks killed 3,409 people in Iraq since the beginning of 2013, according to figures compiled by AFP -- an average of more than 15 dead every day this year.
