BANGKOK - A Thai senator on Wednesday questioned the necessity of the arrival of US troops in Thailand, for joint exercises with their Thai counterparts, despite objections from the government's Center for COVID-19 Situation Administration (CCSA).

A total of 110 US troops arrived from Guam and Japan on Monday and Tuesday for the joint exercise with Thai troops, code-named "Hanuman Guardian 20"

The CCSA said previously in a press briefing that it would pose too much health risk to conduct joint military exercises with countries with high number of COVID-19 cases.
