The offices of Israeli President Moshe Katsav were partially evacuated today amid anthrax fears after an envelope containing suspect white powder arrived at the building.
The letter was addressed to Mr Katsav himself, Israeli public radio said, adding that the whole first floor of the building was evacuated.
The suspicious white powder was sent to a laboratory for analysis.
While there have been scores of anthrax scares in Israel in recent weeks, the incident at the presidential offices were the highest level target yet.
Suspect envelopes which proved to be hoaxes have also been found in the offices of left-wing deputies in the Israeli parliament, the Knesset, and in newspaper offices.
Jerusalam's main postal sorting office was also closed for two days earlier this month and its several hundred employees sent home while a suspicious envelope, posted abroad, was tested and found to be harmless.
