BAGHDAD  - Suicide bombings and other attacks killed 30 people in Iraq Wednesday, and authorities found the bodies of 19 others shot dead in Baghdad, in scenes eerily reminiscent of the country’s sectarian war.

The latest violence, just months ahead of landmark elections, pushed the number of slain so far this year above 6,000 as the country endures its worst prolonged spate of bloodshed since 2008.

Although there have been no claims of responsibility for much of the unrest, authorities are concerned about a resurgent Al-Qaeda, emboldened by the civil war raging in neighbouring Syria.

Four suicide bombers successfully detonated their explosives, but the carnage could have been much worse because security forces shot dead several would-be suicide attackers.

Meanwhile, in two separate areas of the capital, police found the bodies of 14 men, all in their 20s or 30s, and all shot dead, medical officials said.Eight of the corpses were found blindfolded in Dura neighbourhood, while six others had been dumped in a canal in mostly Shuala.

In the northern district of Hurriyah, a family of five - three men and two women - were shot dead in their home in a pre-dawn attack.

Shootings, bombings and mortar fire in various other parts of the capital left five others dead Wednesday. Elsewhere, shootings and bombings - including four suicide attacks - killed 22 people.

In Abu Ghraib, west of Baghdad, a man blew himself up in the middle of a funeral, killing nine people.

In northern Diyala province, a vehicle rigged with explosives and detonated by a suicide attacker killed three members of Kurdish peshmerga forces.

Two separate attacks involving multiple suicide bombers against police near Ramadi, west of Baghdad, killed at least seven policemen and left 15 others wounded. One of the attacks involved a car bomb set off by a suicide attacker on the western outskirts of the city, followed by a firefight between militants and police in which four suicide bombers blew themselves up. Five policemen were killed and 11 were wounded. A separate suicide bombing at a police station just north of the city killed two more policemen and left four wounded.

Ramadi is the capital of the western desert province of Anbar, which shares a long border with Syria. Sunni militants linked to Al-Qaeda have exploited the relative lack of security to set up training camps and carry out attacks on both sides of the frontier.

A shooting near Mosul also left two school teachers dead, and an anti-Qaeda militiaman was gunned down in Salaheddin province. More than 6,000 people have been killed so far this year, according to an AFP tally based on reports from security and medical officials.

Prime Minister Nuri al-Maliki used a recent trip to Washington to push for greater intelligence sharing and the timely delivery of new weapons systems in a bid to combat militants, while France and Turkey have offered assistance.
