Washington: The US has issued a world-wide travel alert for its citizens ahead of the Christmas and New Year holidays in the wake of lone-wolf attack in Sydney.
"The lone wolf attack in Sydney, Australia, on December 15 resulting in the deaths of two hostages, is a reminder that US citizens should be extra cautious, maintain a very high level of vigilance, and take appropriate steps to enhance their personal security," the State Department said yesterday.
"This travel alert expires on March 19, 2015. An analysis of past attacks and threat reporting strongly suggests a focus by terrorists not only on the targeting of US government facilities but also on hotels, shopping areas, places of worship, and schools, among other targets, during or coinciding with this holiday period," the state department said
The State Department also asked US citizens abroad should be mindful that terrorist groups and those inspired by them can pose unpredictable threats in public venues.
"US citizens should remain alert to local conditions and for signs of danger," it added.
Three hostages were killed at a cafe in Sydney on Monday in which a lone heavily-armed man of Iranian-origin held 17 people hostage.
