Yes, I do not think it is safe to travel to Thailand because insurgents are targeting tourist populated areas and people should avoid the country for now until the situation is resolved. In addition, there are a lot of terrorist attacks in major cities around the world hence people should stay put for now until the attacks stop.
While this may seem to be common sense, one should generally not travel to places that are on the terrorist target list. In fact, once terrorists have targeted those areas, and when it is recent, it should be understood that travel to that place should be severely limited. It is unsafe.
Thailand has been a target for terrorists for many years. The government lacks the intelligence capabilities of many other countries that are activity battling terrorist attacks. Until the country demonstrates that is has some reasonable ability to predict and prevent such attacks, it is a bad idea to travel there.
Insurgent activity has now rocked Thailand with a number of bombs hitting a popular tourist destination. This requires people to travel with much more caution in the region. Tourists should be aware of the risks associated with traveling there and know that it is much less safe to travel in a region that has suffered insurgent attacks.
