Anti-Marcos groups hold protests on Bonifacio Day

Metro Manila (CNN Philippines) — The mass action at the People Power Monument against the burial of former President Ferdinand Marcos at the Libingan ng mga Bayani continued well into the night on Wednesday although the crowd had begun to thin out late in the evening.

The protesters were mostly young people or "millennials" from groups called Coalition Against the Marcos burial in LNMB and Millennials Against Dictators.

Martial law victims and their families also attended, along with several artists and performers.

Several government personalities also graced the event like the recently-resigned head of the National Historical Commission of the Philippines (NHCP), Sen. Leila de Lima, former DILG Sec. Mar Roxas, Rep. Edcel Lagman and lawyer Barry Gutierrez.

Protesters called the event Siklab Bayan which they said was aimed at holding the Duterte administration fully accountable for the secret burial of Marcos. They also relived the crimes they claimed the Marcoses have committed during martial law.

They said they would fight for their history, which was once fought for by the real heroes of the country.

Earlier in the day, protesters massed up at various locations in Metro Manila and nearby provinces.

Filipinos abroad were also set to stage their own rally in Vancouver in Canada as well as in parts of the United States like San Francisco, New York, Chicago. A group of Filipinos in Edinburg, Scotland were also joining the protest.

'Occupy Libingan ng mga Bayani'

The group "Occupy Libingan ng mga Bayani" headed to the Liwasang Bonifacio in Caloocan, where the anti-Marcos groups were set to convene. From there, the group marched to Mendiola, then headed to the People Power Monument along Edsa to join other groups.

They stayed overnight ahead of the mass protests, camping out in an area close to the gates of the Libingan ng mga Bayani.

The organizers said the group was a diverse crowd composed of students, young professionals, even martial law victims. They have been exchanging stories about the martial law era and sharing ideas on what they can do to counter attempts to revise history.

The group said they would not stop protesting until the remains of Marcos were exhumed from the Libingan.

They added his burial there was tantamount to denying a dark chapter in Philippine history, because for them, Marcos was not a hero — but a dictator and a plunderer.

They encouraged Filipinos to join the protesters in a show of unity against the rise to power of the Marcoses and against historical revisionism.
