Israeli officials said on Monday that they are examining an envelope containing unidentified white powder that was sent to the Turkish Embassy in Tel Aviv, according to Israeli Army Radio.
Police, firefighters and a hazmat (hazardous materials) team were called to the embassy, and an investigation has started to identify the powder and the sender, the radio said.
Similar letters, including what officials described as threats and drawn swastikas were sent to the U.S., Spanish and Swedish embassies last week, Xinhua reported.
Two employees from the U.S. embassy who handled the envelope underwent an emergency outdoor shower.
There were no injuries in any of those incidents.
