Police in Berlin have confirmed envelopes containing a white powder were sent to the American and Israeli embassies in the German capital.
Police spokeswoman Kerstin Ismer would not confirm whether or not the powder was a dangerous substance, according to the AP news agency.
Two investigations are underway on suspicion of disturbing the peace by threatening a crime.
The Israeli Embassy received its letter on Tuesday July 24, while the US Embassy’s envelope arrived two days later.
