Israeli ambassador to Jordan, Danny Navon, was returning to Israel with his staff on Thursday, fearing a large demonstration planned outside the Ambassy later in the day, Israeli public radio reported.
Jordanian activists have posted calls for a mass rally on social networking site Facebook under the banner "No Zionist embassy on Jordanian territory."
The Israeli foreign ministry spokesman could not immediately be reached for comment.
In Jordan, a foreign ministry spokesman told AFP: "We have not been officially informed of anything."
There were no unusual security measures around the embassy in west Amman on Thursday morning, an AFP correspondent reported, although Israeli radio said Jordanian security forces had put the building under heavy guard.
Jordanian opposition groups, including Islamists, leftists and youth activists, have said they plan to hold their demonstration at around 6:30 pm (1530 GMT).
Last weekend, a mob ransacked Israel's mission in Egypt and the ambassador and his staff were evacuated from the country.
Six Israeli security guards were besieged in the embassy building for several hours before being rescued by Egyptian commandos.
Israeli media said that the Amman embassy staff return to Israel for the Jewish Sabbath every Friday and Saturday but had closed a day early as a precaution.
Jordan and Egypt are the only two Arab states to have signed peace treaties with Israel.
