The US State Department has issued a travel alert worldwide indicating the dangers in travelling due to the activities of terroists.

"Current information suggests that ISIL (aka Da’esh), al-Qa’ida, Boko Haram, and other terrorist groups continue to plan terrorist attacks in multiple regions." A statement on the US State Department website said.

According to the alert "these attacks may employ a wide variety of tactics, using conventional and non-conventional weapons and targeting both official and private interests. "

"Authorities believe the likelihood of terror attacks will continue as members of ISIL/Da’esh return from Syria and Iraq.  Additionally, there is a continuing threat from unaffiliated persons planning attacks inspired by major terrorist organizations but conducted on an individual basis.

"Extremists have targeted large sporting events, theatres, open markets, and aviation services.  In the past year, there have been multiple attacks in France, Nigeria, Denmark, Turkey, and Mali.  ISIL/Da’esh has claimed responsibility for the bombing of a Russian airliner in Egypt. "

The statement said the US continues to work closely with its allies on the threat from international terrorism in order to foil terrorists attacks
