The US State Department doesn’t have any alerts set for Malta, it’s deemed to be at Level 1 in terms of precautions required by visitors, just as much it advices so to countries like Iceland, Luxembourg, Montenegro, Estonia, Latvia, Slovenia, North Macedonia, Lithuania, Croatia, Ireland, Norway, Slovakia, Finland, Bulgaria, Switzerland, Austria. Belarus, Hungary, Sweden, Portgual, Greece, Czech Republic, Moldova, Romania, Poland and Albania.
Level 1 practically means that one should exercise normal precautions
Level 2 means that travellers should exercise increased caution. In fact more attention is being recommended to travellers visiting Denmark (since terrorists potentially “continue plotting possible attacks), United Kingdom (due to terrorist threats that may potentially be ongoing, as well as a risk of isolated violence by “dissident groups in Northern Ireland), Serbia (due to the high occurrence of crime), The Netherlands (since terrorists may attack the Netherlands with little to no warning), Russia (as crime, terrorism, and arbitrary enforcement of local laws throughout Russia may put Americans in unsafe situations), Ukraine due to crime, civil unrest, and demonstrations that occur around elections. Tourists should take care not to travel to Crimea, due to “arbitrary detentions and other abuses by Russian occupation authorities,” and should avoid the eastern parts of the Donetsk and Luhansk oblasts due to armed conflict), Bosnia Herzegovina (due to the threats of terrorism and land mines), France (due to terrorism and civil unrest), Belgium (due to potential terrorist attacks), Spain (as terrorist groups may continue to plot attacks), Italy (due to potential terrorist attacks that may target popular tourist locations and both public and private spaces), Germany (as terrorist groups may “continue plotting possible attacks”).
Travellers who were thinking of going to countries classified at Level 3 should reconsider travel, while those marked at Level 4 are countries were one should not travel.
There are several countries in Africa, Latin America, South America, and the Middle East ranked Levels 3 and 4. These include Venezuela, multiple regions in Mexico, Libya, Sudan, Somalia, Yemen, Iraq, Iran, Afghanistan, and North Korea.
