MANILA (7th UPDATE) - The mayor of Calbayog City in Samar was killed on Monday in an incident surrounded by conflicting reports on whether it was an ambush or a shootout.

Mayor Ronaldo Aquino is the latest local official slain under President Rodrigo Duterte's administration. His death has brought to 25 the tally of local executives killed in this administration.

Reports from police said Aquino was in the vehicle when the incident happened at the Laboyao Bridge in Barangay Lonoy, Calbayog City around 5:30 p.m.
