The United States has warned Americans in Turkey to exercise "extreme" caution upon visiting tourist destinations, particularly in the cities of Istanbul and Antalya.
In an “emergency message” to its citizens, the US embassy issued the warning on Saturday, saying, “There are credible threats to tourist areas, in particular to public squares and docks in Istanbul and Antalya."
The statement was emailed to US citizens in Turkey.
The country has been the scene of several bomb attacks this year. The most recent one occurred last month in Istanbul's main shopping district and killed three people.
Back in March, the US embassy issued a warning to Americans in Turkey, advising them to stay away from the capital Ankara’s city center, due to a “potential terrorist plot to attack Turkish government buildings and housing located in the Bahcelievler area of Ankara.”
Two days later, a massive explosion hit the center of the capital, killing at least 37 people and injuring 125 others. Another bombing in Istanbul left at least ten people dead back in January. The attack was blamed on the Daesh Takfiri terrorist group.
Turkey has been part of the so-called US-led coalition against Daesh, but it has long supported the militants.
Ankara is among the main supporters of some militant groups operating in Syria, with reports saying that it actively trains and arms Daesh terrorists there and facilitates their safe passage into the Arab country.
It has also been engaged in a large-scale campaign against the Kurdistan Worker's Party (PKK) militants in its southern border region in the past few months. The Turkish military has been pounding the group’s positions in northern Iraq as well.
