The United States Embassy in Manila urged Americans in the country to avoid the sites of the anti-corruption rallies set to take place across the Philippines on Sept 21 in protest against what organizers say is widespread corruption in the government.

US citizens were advised to avoid areas of demonstrations, which will also coincide with the 53rd anniversary of the declaration of martial law by former President Ferdinand Marcos Sr.

A broad coalition of students, church groups, civil society organizations, labor unions, and political coalitions are expected to join the demonstrations,” the embassy said.

“US citizens should avoid these demonstrations due to the potential for violence,” the embassy said.

Americans should “exercise caution when in the vicinity of any large gatherings, as even peaceful demonstrations have the potential to turn violent without warning,” it added.

They are also advised to follow local media and government sources for updates on possible disruptions due to protest activity.

Various groups have organized rallies in the capital and other cities across the country to express their outrage over massive corruption on flood-control projects involving lawmakers, public works employees and private contractors. Security forces have been placed on alert.

The embassy asked US citizens to follow instructions from local authorities.
