Thailand has revived a controversial law against criticising the royal family in an attempt to curb months of anti-government protests.Several activists have been summoned to face charges under the lèse-majesté law, which carries a sentence of up to 15 years in prison for each count, BBC reported.
It is the first time in over two years that such charges have been filed.
Thailand has been rocked by student-led protests for months, with demonstrators demanding changes to the monarchy.
Protesters are also calling for constitutional reforms and the removal of the country's prime minister.
At least six other key protest leaders, including human rights lawyer Anon Nampa and Panusaya Sithijirawattanakul, are expected to face the same charges, according to reports.
Thailand's lèse-majesté law, which forbids any insult to the monarchy, is among the strictest in the world.The reintroduction of charges under the lèse-majesté law comes ahead of a planned demonstration on Wednesday at the Crown Property Bureau, an institution that controls the royal fortune on behalf of the monarchy, located in the capital, Bangkok.
This latest development follows increasingly outspoken criticism of the king by protesters.
King Vajiralongkorn has been criticised for spending much of his time in Germany.
