The Indian Embassy cautioned Indian tourists and residents to take usual precautions for personal safety and advised them to monitor the situation in Bangkok through media reports, tour operators and their hotels.
This is a notice to Indian nationals and not a travel advisory, Embassy sources told PTI.
Thailand is a top tourist destination for Indian tourists.
The notice came in the wake of mass political protests that spread outside the capital today, demanding the resignation of Prime Minister Yingluck Shinawatra.
