Turkish President Recep Tayyip Erdogan on Tuesday said Israelinfo-icon should "review" its support for Iraqi Kurdish independence, warning the Jewish state's support for the bid could negatively affect diplomatic ties between Ankara and Jerusaleminfo-icon.

"If they do not review, we cannot take a lot of steps that we were about to take with Israel," Erdogan was quoted by the official Anadolu news agency as saying.

 "It is not possible for usinfo-icon to take steps with those who do not see Turkeyinfo-icon as a playmaker in the region. Turkey is a playmaker in the region," he said.

Despite years of close security and intelligence ties, Israel's diplomatic relations with Turkey have been frosty under Erdogan's rule, reaching a nadir after Israeli troops raided the Gazainfo-icon-bound Mavi Marmara ship and killed nine Turkish nationals, who attacked them violently aboard, in May 2010.

Although Jerusalem and Ankara struck a reconciliation deal in August 2016 after years of severed ties following the flotilla incident, Erdogan has continued to publicly chastise Israel in harsh terms over its policies towards the Palestinians and the Temple Mount in Jerusalem.

"Who will recognize your independence? Israel. The worldinfo-icon is not about Israel. You should know that the waving of Israeli flags there will not save you," he said, according to the Hurriyet daily.Erdogan also said Israel's support for Kurdish independence would not confer on the referendum results "innocence nor legitimacy."

In addition to Erdogan's threat against Israel over its support for the referendum, Turkish nationalists have claimed the independence vote is meant to create a "second Israel." A conservative newspaper loyal to Erdogan has pointed to the presence of Israeli flags alongside "so-called Kurdish flags" at rallies organized by the Kurdistan Democratic Party (KDP) and claimed that the referendum was part of a "Zionist plot."

Top Iranian officials have also claimed that the Kurdish independence referendum is part of an Israeli scheme, with Supreme Leader Ayatollah Ali Khamenei's chief of staff saying Tuesday that the vote was a "Zionist plot" meant to fuel violence in the Middle Eastinfo-icon, following the battlefield defeats in Iraqinfo-icon and Syriainfo-icon suffered by the Islamic Stateinfo-icon terror group.

Turkey, Syria and Iraninfo-icon, all of which have their own sizable Kurdish minorities, have all strongly condemned the independence referendum, as has Iraq's federal government.

While Isreali Prime Minister Benjamin Netanyahu has voiced his backing for Kurdish independence, on Monday he instructed ministers in his government to avoid speaking out about the referendum in Iraqi Kurdistan.

Reuters quoted an unnamed Israeli cabinet minister as saying that "Bibi [Netanyahu] asked us not to" comment on the referendum because it was "too sensitive."

Monday's referendum in Iraqi Kurdistan was openly opposed by both the US and Turkey, who may have pressured Netanyahu not to express support for the vote.

Similarly, some Kurdish leaders have balked at overt support from Israel, as they face charges from Arab, Turkish and Iranian leaders that an independent Kurdish state would be a potential "second Israel" -- that is, an enemy -- in their midst.

However, some Kurds have flaunted support from and ties with the Jewish state, waving Israeli flags at pro-independence rallies.

Results of Monday's referendum, which are nonbinding, are set to be announced later Tuesday, with many expecting a resounding "yes" vote.
