A senior Iranian MP called on Turkey to expose the "Zionist kidnappers" of a former deputy defence minister who went missing in Istanbul in 2007, Fars news agency reported on Sunday.
Asgari, a former deputy Defense Minister, allegedly disappeared in Turkey in 2007.
"Turkey is expected to release the names of the terrorists from the Mossad spy agency," the head of parliament's national security and foreign policy commission Alaeddin Borujerdi said.
"Those who had a role in kidnapping (Ali Reza) Asghari in Turkey should be named so the Zionists' crime is fully exposed," he added.
Turkey is a close ally of Iran and is set to host the next round of talks between Tehran and six world powers over the Islamic republic's nuclear programme.
On Friday, acting foreign minister Ali Akbar Salehi, following reports that Asghari may have died in an Israeli jail, asked UN chief Ban Ki-moon for help in discovering his fate.
Salehi's appeal to the UN chief came after Iranian officials and media cited reports posted on Israeli news websites which alleged that Asghari had died in an Israeli prison.
