Manila: Gunshots were heard at the Senate of the Philippines on Wednesday, where Senator Ronald dela Rosa remains under protective custody after facing an arrest warrant from the International Criminal Court, according to local media reports.

According to Anadolu Agency, Senate Secretary Mark Llandro Mendoza informed reporters that there have not yet been any casualties after shots were fired. The situation is still being assessed after an undetermined number of law enforcers attempted to enter the building, he said.

Personnel from the military, police, and National Bureau of Investigation had earlier arrived at the Senate, as reported by GMA News Online. There is an ongoing lockdown at the upper chamber, where Senator dela Rosa remains under protective custody.

Dela Rosa faces a warrant over charges of crimes against humanity committed between July 2016 and April 2018, during which at least 32 people were reportedly killed. He served as the police chief under former President Rodrigo Duterte, who has been detained in The Hague since March while facing three counts of crimes against humanity linked to at least 78 alleged killings during his presidency.

Senator dela Rosa was placed under Senate protective custody on Monday after attending a session for the first time since November 2025.
