An envelope containing “suspicion powder” was sent to the Knesset office of Israeli Health Minister Uriel Buso, Israeli media reported on Tuesday.

In accordance with protocol, police were notified and the envelope along with the suspicious substance were transferred for further examination by the appropriate authorities, Israel Hayom reported.

A package containing a suspicious powder was also sent to Buso’s office in June. The minister was examined by medics and found not to be showing any symptoms after opening the package. However, his office was temporarily shut down following the incident.
