Federal Bureau of Investigation made clear that while the agency isn't aware of a specific, credible threat to the USA homeland, authorities must remain vigilant and report any suspicious activity to the Federal Bureau of Investigation or other appropriate authorities. "We encourage any affected USA citizens who need assistance to contact the U.S Embassy in London and follow Department of State guidance", the statement read.

"We are now treating this as a terrorist incident until we have further information", Hopkins said. "So we work closely with them".

ABC News has additionally learned that state and local fusion centers across the country - which include representatives from local, state and federal agencies - are working to identify potentially vulnerable "open venues" and upcoming events in their regions, so that they can help local police put together their latest security plans for those events and venues.

At 9 a.m. United Kingdom time on Tuesday, an emergency meeting of COBR - which stands for Cabinet Office Briefing Room and is pronounced "Cobra" - will take place at Downing Street in London.
