A series of blasts rocked Iraq’s capital Baghdad on Tuesday afternoon killing at least 31 people and injuring dozens of others, Agence France Presse reported citing official sources.

Vehicles rigged with explosives went off minutes apart at around 6:00 pm (1500 GMT) in packed commercial areas of Shuala, Kamiliyah, Shaab and Abu Tcheer neighbourhoods, leaving a total of 31 dead and 61 wounded, according to security and medical officials.

Five car bombs targeting markets in both Sunni and Shiite areas of the city struck at around 15:00 GMT, according to an official from the interior ministry and medical sources.

No group immediately claimed responsibility for the attacks, but most of the violence struck Shiite targets.

Shootings elsewhere in the capital killed four others, while bombings in the restive northern cities of Kirkuk and Mosul left one person dead and three wounded.

The violence comes a day after a series of attacks north of Baghdad left 45 people dead, including 23 killed when a suicide bomber blew himself up in the middle of a funeral taking place inside a religious hall.

Tuesday's attacks come a day after the United Nations announced that more than 2,500 Iraqis have died in violent attacks since April this year, with May – which saw over 1,000 people killed - being the deadliest month since the height of sectarian bloodletting in 2006-07.In June, 761 people fell victim to militant attacks in different parts of the country.
