The British Olympic Association (BOA) has confirmed they have received an email containing terrorist threats ahead of next month's Winter Olympics in Sochi, Russia.
The BOA's director of communications Darryl Seibel believes the threat "lacks credibility" and insisted they will not alter the strict security arrangements already in place to protect the Great Britain team.
But the federations representing Italy, Germany, Hungary and Slovenia have also indicated they have received similar threats, which were passed to the International Olympic Committee (IOC) security advisers for inspection.
"We have received what appears to be the same e-mail that many other federations have received and the IOC has responded to state very clearly that in their view there is nothing of substance to this," said Seibel.
"In addition we have had our own experts take a look at this and they have responded in exactly the same way by stating that this is nothing credible.
"Organisations like ours receive correspondence of every type and it is not uncommon to come across something like this that lacks credibility.
"It is extremely important in matters such as this that everyone maintains a level head and a sensible perspective."
The IOC also dismissed the latest threat but was keen to stress they take all threats seriously in the initial stages.
"The IOC takes security very seriously and passes on any credible information to the relevant security services," read an official IOC statement.
"However, in this case it seems like the email sent to a number of NOCs
(National Olympic Committees) contains no threat and appears to be a random
message from a member of the public."
The federations of Italy, Germany, Hungary and Slovenia are also understood to have received similar letters.
A statement from the Italian Olympic Committee (CONI) read: "CONI announces it has received this morning an email containing terrorist threats in view of the 2014 Olympic Winter Games in Sochi.
"From what CONI is aware, an analogue mail has been sent to the IOC (International Olympic Committee) and to other Olympic Committees.
"CONI has transmitted the content of the mail to the given authority in charge of international security.
"At the same time the Italian Olympic Committee wishes to state trust and serenity in the safety measures that have been guaranteed by the IOC organisers, the international federations and the Olympic Committee."
The Winter Olympics runs from February 6-23.
