BAGHDAD (Reuters) - Iraq will take "all the necessary measures" to prevent cross-border attacks by Islamic State militants in Syria, Iraqi Prime Minister Haider al-Abadi said on Tuesday.
Last year Iraqi warplanes carried out at least one strike on Islamic State targets inside Syria, in coordination with the U.S.-led anti-Islamic State coalition and with the approval of the Syrian government.
"Daesh are present in eastern Syria, at the Iraqi border. I will take all necessary measures if they threaten the security Iraq," Abadi told a news conference in Baghdad. He said he had communicated this position to U.S President Donald Trump on the telephone on Sunday.
He said he had asked the country's military command "to lay out all possible plans, as I am keen to protect Iraqi citizens" from cross-border attacks.
An expert close to the Baghdad government told Reuters last week that Iraq may carry out special forces operations against Islamic State militants in Syria.
While troops could be dropped into Syria, the plan did not at this stage involve sending ground forces over the border, Hisham al-Hashimi, who advises several governments on Islamic State, including Iraq's, told Reuters.
Iraq has good relations with Iran and Russia, Syrian President Bashar al-Assad's main backers in the seven-year Syrian civil war, while it also has strong support from the U.S.-led coalition.
Abadi declared victory over Islamic State within Iraq in December, although the militants have continued to carry out ambushes, assassinations and bombings across the country.
U.S.-backed Iraqi forces dislodged the militants from Mosul, their de facto capital in the north of the country, putting an end to the cross-border "caliphate" they declared in 2014.
Special forces from a number of countries already operate in Syria, including the United States, Russia and Iran. Turkey has also sent in ground forces to push Kurdish fighters away from its border.
