A Philippine police official says law enforcers have killed 13 drug suspects and arrested more than 100 suspected dealers and criminals in 24 hours of raids in a province with a record of bloody crackdowns.

Police Senior Superintendent Romeo Caramat Jr. says the 13 drug suspects were killed Wednesday in gunbattles with police in a city and eight towns in Bulacan province just north of Manila. More than 70 raids were launched by the police in Bulacan that day, leading to the arrests of 109 people, including 92 suspected drug dealers and users.

The latest violence raises the death toll in President Rodrigo Duterte's anti-drug crackdown to 4,239 since it was launched in July 2016. The U.S. and European countries have expressed alarm over the drug killings.
