Rabat, March 22 -- The UK has updated its foreign travel advisory for Morocco, advising its citizens to be "vigilant at all times."

The UK said that "terrorists are very likely to try to carry out attacks in Morocco," recalling the Imlil murders when terrorists decapitated two Scandinavian tourists decapitated near Mount Toubkal.

Britain also warned that "attacks could be indiscriminate or target foreigners."

The warning mentioned the April 2011 terror attack when "17 people were killed and 25 injured in a large explosion caused by a bomb in Marrakech at the Argana restaurant in Djema el-Fna Square."
