On Monday, British security firm AKE Group warned that "terrorists in Iraq may be planning mass casualty explosive attacks against large gatherings of civilians to mark the end of Ramadan later this week".
"We haven't received any specific intelligence on the matter but they (insurgents) may be 'saving up' their willing bombers for the closing period of the month, due around 17-18 August," AKE analyst John Drake said.
Official figures put the number of people killed in attacks in July at 325, the highest monthly death toll since August 2010.
