Heavy rainfall across Istanbul has led to severe disruptions in both transportation and daily life, while simultaneously providing a much-needed boost to the city's water reserves.

In a tragic incident linked to the adverse weather conditions, a police service vehicle crashed on the Northern Marmara Highway, resulting in the death of one officer and injuries to 16 others.
