Israel warned its citizens of possible terrorist attacks targeting them abroad.

An unnamed official with Israel’s Counterterrorism Bureau told reporters Friday that intelligence gained from the foiled Iranian attackers in Bangkok indicated that more attacks are in the works, Haaretz reported.

“I call on Israelis abroad to show awareness and take basic steps to reduce possible harm,” the official said, adding that they should “take note of suspicious objects and refrain from taking packages from strangers” and “be attentive to the directives of local security forces.”

The warning comes after an accidental explosion in the Thai capital on Tuesday that led to the arrest of three Iranians. Police say Israeli diplomatic staff were the intended targets.

Earlier in the week, bombs targeting Israeli diplomats were detonated in Georgia and India. The wife of an Israeli envoy was injured.
