Washington — The State Department is advising US citizens traveling in Europe to be aware of a "heightened risk of terrorist attacks" during the holiday season.
In June this year the US issued a similar European-wide alert, later following with a specific alert for South Africa, warning of "terror attacks by Islamic militants on Americans in South Africa".
No alert has as yet been issued for South Africa.

The advisory issued on Monday says "credible information" indicates that Islamic State and al-Qaida militants continue to plan attacks in Europe around the holiday season. It also warns that "extremist sympathizers or self-radicalized extremists" may try to execute attacks.
The department is encouraging travellers to be cautious at holiday festivals and outdoor markets. It is urging Americans to avoid large crowds and be vigilant when visiting tourist sites, riding public transportation and meeting in places of worship, hotels, restaurants and other gathering spots.
The advisory praises European efforts to disrupt plots, but says the US remains concerned about the potential for attacks.
