JERUSALEM, June 19 (Xinhua) -- Israeli Prime Minister Naftali Bennett on Sunday warned Iran against "attempts to orchestrate attacks against Israelis overseas," threatening that Israel will exact a price for attempts to harm its citizens.

Making the remarks at the weekly cabinet meeting, Bennett said "we are currently witnessing Iranian attempts to attack Israelis in various overseas locations," adding that "Iran's plans focus on Turkey" while Israeli security services "are working to thwart attempted attacks before they are launched."

Israel will "strike those who send the terrorists and those who send those who send them," Bennett warned, saying "our new rule is: whoever sends -- pays," according to a statement issued on his behalf.

The prime minister also reiterates a call for Israelis to avoid traveling to Turkey, especially Istanbul, if it was not necessary.

Also on Sunday, Israeli President Isaac Herzog and Turkish President Recep Tayyip Erdogan talked over phone about the "Iranian intentions to perpetrate terror attacks against Israelis in Istanbul," Herzog's office said in a statement.

Herzog thanked Erdogan for Turkey's efforts to thwart attacks on Turkish soil, stressing that the threat to Israelis has not yet passed and "the counterterror efforts must continue."

The two leaders also highlighted the great contribution of this cooperation to the trust being built between the governments and nations, the office said.

On Saturday, Israel's Channel 12 TV news reported Israel's intelligence agency Mossad and Turkish intelligence services thwarted an attack earlier on the day. There was no official confirmation for the report.

Israel's National Security Council on Monday raised its travel warning for Istanbul, Turkey's largest city, to the highest level, citing possible attacks by Iran, said a statement from the council.

The council called on Israelis currently in Istanbul to leave the city and Israelis planning to travel to Turkey to avoid doing so until further notice.

Iran has not commented on the Israeli allegations.

Iran has accused Israel of killing on May 22 Hassan Sayyad Khodaei, an Islamic Revolution Guards Corps colonel, and has vowed to avenge his death. Khodaei was shot and killed by two motorcyclists in the east of Tehran, Iran's capital.
