Thai protesters wake up on the second day of a rally demanding reforms to the country's government and monarchy today (September 20).

Activists camped out overnight on the Sanam Luang, or Royal Field, in front of the Grand Palace in Bangkok after breaking through police barricades on Saturday.

A symbolic plaque proclaiming the country ''belongs to the people'' was cemented into the ground of the sacred field - normally used for royal cremations and other ceremonies - before the protesters continued a march to the Grand Palace to hand over a letter demanding reforms.

There were also demonstrations in New York, Tokyo and London on Saturday. Activists are calling for democratic reforms following a 2014 military coup and elections in 2019 that strengthened the army's grip on power.

The focus of the unrest has also shifted towards the country's monarchy, which is protected from criticism by strict Lese Majeste laws.
