The Israeli Postal Authority has introduced tighter screening methods at its sorting offices to counter the threat of a bioterrorist attack.
The authority's spokesman said it was in contact with postal authorities in the United States, as well as with the Israeli army and police, to ensure against an anthrax attack in Israel.
The spokesman also said the authority had received about six to ten suspicious envelopes which had been sent for testing, but that no anthrax had been discovered so far.
He said that since the September 11 terrorist attacks in the United States, supervision of incoming and outgoing mail, including packages, had been increased.
But tight postal security is not new to Israel, whose guard has been up since the 1970s when Palestinian and Israeli intelligence services used the letter bomb as a weapon of choice in targeting guerrillas, operatives and diplomats.
Since then, notices in post offices have continually warned people to be on the look-out for suspicious letters and packages.
Even the slots on Israeli post boxes are extremely thin as an added measure against potentially explosive-laden mail.
The Israel Postal Authority handles around 2.2 (m) million pieces of mail every day.
