Three suicide vehicle bombs in Baghdad on Sunday bear the mark of Al-Qaeda, but it is too early to say definitively who was behind the attacks, Iraqi Foreign Minister Hoshyar Zebari told AFP.
"It looks like (Al-Qaeda)," Zebari said in a telephone interview following the blasts, which killed 30 people and left 168 wounded.
"I really feel it's early, however, unless we ensure the investigation is complete" to say for sure who was behind the bombings which hit diplomatic missions across the Iraqi capital, he added.
"They bear the same marks of previous attacks, in the timing, the targeting, the simultaneous attacks on different targets in different places to have maximum impact," he added, referring to co-ordinated bombings in August, October, December and January that left more than 400 dead in total.
The bombings came as Iraqi political parties negotiate to form a government, nearly a month after a general election that left four main blocs, none with sufficient seats to form a parliamentary majority on their own.
Security officials have warned that a protracted period of coalition building could give insurgents an opportunity to further destabilise Iraq.
"This is a political attack, aimed at derailing the process, sending a message that the terrorists are still in business," Zebari said.
"Because of the vacuum of forming the next government, they wanted to send that message."
