JAKARTA, May 23 (CGTN) -- Calm returned to the streets of central Jakarta on Thursday after a second night of clashes between security forces and protesters.

The last remaining protesters had dispersed by 7 a.m., according to Dedi Praseyto, a Jakarta police spokesman.

Downtown areas of the capital were still a battlefield of tear gas, rubber bullets, rocks and firecrackers on Wednesday, with protesters tearing up slabs of pavement, destroying street signs and setting fire to food stalls and a security, expressing their anger over the outcome of last month's election.

The unrest started when the General Election Commission confirmed that President Joko Widodo had won the second term by beating his challenger, former general Prabowo Subianto in the April 17 poll.

Six people were killed in the first night of rioting, which was concentrated in the sprawling textile market neighborhood of Tanah Abang, said Jakarta Governor Anies Baswedan.

Three hospitals had treated more than 350 people for injuries, state news agency Antara reported.
