A 4.0 magnitude earthquake in the Marmara Sea shook Istanbul in the morning, causing a balcony collapse in Bahçelievler with one person injured. The tremor, measured at 3.7 by AFAD and 4.0 by Kandilli Observatory, represents continued seismic activity following the major earthquake on April 23rd.

The day's most significant development was the death of DEM Party MP and Deputy Parliament Speaker Sırrı Süreyya Önder after 19 days in intensive care. Condolence messages poured in from across the political spectrum, including President Erdoğan, MHP leader Bahçeli, and even Abdullah Öcalan from prison.

President Erdoğan visited Northern Cyprus for the opening of the new KKTC Presidential Complex, emphasizing Turkey's continued support for the territory. The Foreign Ministry also clarified that Turkish airspace remains closed to Israel, contradicting reports that Netanyahu might use it for an Azerbaijan visit, which was subsequently postponed.
