Interpol said on Tuesday it had issued an international Red Notice for the arrest of Iraq's fugitive Vice President Tareq al-Hashemi "on suspicion of guiding and financing terrorist attacks".
"The Red Notice for al-Hashemi represents a regional and international alert to all of Interpol's 190 member countries to seek their help in locating and arresting him," the Lyon-based international police agency said.
Interpol said the notice, its highest possible alert, was issued following an Iraqi warrant made "as part of an investigation in which security forces seized bombing materials and arrested individuals".
Hashemi, who is being tried in absentia in a Baghdad court and was last known on May 4 to be in Istanbul, is charged along with several bodyguards with killing six judges and senior officials.
He has challenged the legitimacy of the trial and said his life is at risk in Baghdad.
"The Interpol Red Notice against Tareq al-Hashemi will significantly restrict his ability to travel and cross international borders," Interpol secretary general Ronald Noble said in a statement.
"This case also clearly demonstrates the commitment of Iraqi authorities to work with the world police community via Interpol to apprehend individuals facing serious charges," he said.
A Red Notice is not an internationally binding arrest warrant but many of Interpol's members consider it a valid request, especially if they have an extradition treaty with the requesting country.
