TAIPEI — People intending to visit France should be mindful of their personal safety as the French police have been tipped off to possible terrorist attacks, the Ministry of Foreign Affairs said yesterday. The ministry’s Bureau of Consular Affairs also advised local citizens to avoid visiting areas near the G-20 Summit venue in Seoul, South Korea when the city hosts the summit on Nov. 11 and Nov. 12. The bureau said in a statement that France’s four-tier national security alert system remains at the highest “red” level, which means the country faces threats of major terrorist attacks and should have disaster-relief and counterattack measures in place. Thus, those traveling in France or intending to go there soon should be on alert, particularly when taking subways and trains or flying to one’s destination, the statement said. Meanwhile, some South Korean activist groups are preparing to stage protests when the G-20 summit takes place in their capital city, the ministry said. It urged local citizens to avoid traveling to the meeting venue when visiting the country during the summit period because protest activities could turn ugly or erupt into violence. The U.S. Department of State issued a travel advisory on Oct. 27 suggesting that American citizens refrain from visiting Seoul during the G-20 summit.
