Gunshots rang out inside the Philippine Senate building in Manila on Wednesday, May 13, 2026 [1], during a standoff to arrest Senator Ronald dela Rosa.

The incident represents a violent escalation in the Philippine government's struggle with the International Criminal Court (ICC), highlighting the tension between national legislative immunity and international legal mandates.

Authorities moved to arrest dela Rosa, a former police chief, who is wanted by the ICC for alleged crimes [2]. According to reports, the senator resisted the arrest by taking refuge inside the Senate chamber [3]. This move prompted his supporters to mobilize, which led to a violent confrontation between the lawmaker's allies and Philippine police and troops [3].

Senate President Alan Peter Cayetano confirmed the volatility of the situation within the government complex. "We are hearing gunshots inside the Senate building," Cayetano said [4].

The senator had previously indicated that his capture was expected. "My arrest is imminent," dela Rosa said [5].

The standoff occurred as security forces attempted to breach the Senate to secure the suspect [2]. The presence of troops and police inside a legislative building is a rare occurrence in Manila, marking a significant breach of the traditional sanctuary provided to lawmakers. The exact number of casualties or injuries from the gunfire has not yet been verified in the available reports [1].

This confrontation follows a long period of friction regarding the ICC's jurisdiction over former officials. The attempt to seize dela Rosa by force suggests that the window for a peaceful surrender or a negotiated legal process has closed [3].

"We are hearing gunshots inside the Senate building."

This event signals a breakdown in the diplomatic and legal norms governing the Philippine Senate's role as a sanctuary for its members. By attempting a forced arrest of an ICC suspect within the legislative chamber, the Philippine executive and security apparatus are prioritizing international legal obligations or internal political shifts over parliamentary immunity, potentially setting a precedent for future arrests of high-ranking officials.
