Turkey cast doubt on Friday over allegations that
Iranian agents plotted to kill the Saudi ambassador in Washington, saying it did not believe Iran would be engaged in such an act.
"We don't believe that Iran would be engaged in such an act, but America says they have evidence," Ahmet Davutoglu, Turkey's foreign minister, told a joint news conference with his visiting Iranian counterpart Ali Akbar Salehi.

Those who make the claims should also be clear about their claims, and Iran should answer to that," Davutoglu said.
Tehran has denied the allegations, saying they are part of a smear campaign. Salehi said it was a "waste of time" to talk about the accusations.
Davutoglu later said in comments to state-run new agency Anatolian that the US allegations were "serious" and urged Iran to be fully transparent.
"Claims that a country will assassinate another country's ambassador in a third country are very serious and should be handled with care and seriousness," Davutoglu said.
"Our advice to our neighbor Iran is to pay attention to the evidence the US has and be helpful with full transparency during the process."
The affair has aggravated tensions between the United States and Iran. Davutoglu called on the United States and Iran to address their differences constructively.
"What needs to be done now is that all parties involved share what they have and clear the issue without giving way to a further increase in tensions. Turkey is ready to contribute if there is anything we can do to help relieve the tension."
Turkish media reported this week that the United States had sent representatives to Turkey to present evidence of the alleged plot and discuss the allegations with Turkish officials.
A US embassy spokesman would not comment on the reports. "Our position on this issue is well known," he said.
European Union governments agreed on Friday to
impose sanctions on five people linked to the alleged plot, after Britain froze the assets of five men, including the two central suspects.
Turkey, which has built up strong trade and political ties over the last years with Iran, has been out of step with the US stance toward Tehran in the past, but it agreed last month to host a radar system for a NATO missile shield program.
Turkey says it observes United Nations sanctions against Iran but says it is not obligated to adhere to a separate set of US and European sanctions.
