An army helicopter flies low over the heads of demonstrators in Sri Lanka. The Prime Minister Ranil Wickremesinghe has instructed the military and police "to do what is necessary to restore order".

Sri Lankans continued to stream into the presidential palace. A growing line of people waited to enter the residence, many of whom had traveled from outside Colombo on public transport.
