BAGHDAD, Iraq?July was the deadliest month in Iraq since May 2008 with a total of 535 people killed across the country as a result of violence, according to government figures released on Saturday.

The figures show a sharp upswing in the level of violence nearly five months after parliamentary elections which have yet to result in the formation of a new government and as the United States continues a major withdrawal of its forces.

A total of 396 civilians, 89 policemen, and 50 soldiers died in attacks in July, data compiled by the health, defense, and interior ministries showed.

The death toll is the highest for a single month since May 2008 when 563 people were killed in violence.

Saturday's figures also showed that 1,043 people?680 civilians, 198 policemen, and 165 soldiers?were injured in attacks this month, the highest such number this year.

The data also showed that 100 insurgents were killed and 955 were arrested.

US and Iraqi officials have warned of the dangers of an upsurge in violence if negotiations on forming a new government drag on, giving insurgent groups an opportunity to further destabilize the country.

Nearly five months since the March 7 general election which gave no single bloc an overall parliamentary majority, the two lists which won the most seats are still bickering over who should be the next prime minister.

Both former premier Iyad Allawi and incumbent Prime Minister Nuri al-Maliki insist that they are best placed to tackle the war-torn country's insecurity and shaky public services.

Four American soldiers died in July?only one in a hostile incident?bringing to 4,413 the total number to have died in Iraq since the US-led invasion in 2003 that toppled dictator Saddam Hussein, according to an AFP tally based on figures from independent website www.icasualties.org.

The latest figures come as the US military carries out a steady drawdown of its forces in Iraq, and a month before it concludes combat operations in the country.

There are approximately 65,000 American soldiers currently stationed in Iraq, but that figure is set to drop to 50,000 by September 1. All US troops must withdraw from Iraq by the end of 2011, in line with the terms of a US-Iraq pact.
