Israel on Monday signaled it could attack suspected Iranian military assets in Iraq, as it has done with scores of airstrikes in war-torn Syria.

Citing Iranian, Iraqi and Western sources, Reuters reported last week that Iran had transferred short-range ballistic missiles to Shiite allies in Iraq in recent months. Tehran and Baghdad formally denied that report.

Israel sees in Iran's regional expansion an attempt to open up new fronts against it. Israel has repeatedly launched attacks in Syria to prevent any entrenchment of Iranian forces helping Damascus in the war.
