The suspect in the attack at Berlin's Christopher Street Day event is dead, according to multiple German media reports.

Public broadcaster rbb reported that Abdul Ballout was located at a garden allotment in Berlin. German tabloid BILD said police officers were deployed to the city's Spandau district, where witnesses reported hearing gunshots.

The arrest followed an hours-long manhunt across Berlin, with police carrying out searches across the city and at railway stations, airports and border crossings.

Earlier in the day, German Interior Minister Alexander Dobrindt (CSU) confirmed that a woman was killed in Saturday evening's attack on Berlin's Christopher Street Day (CSD) and 29 people were injured, some seriously, a number of them critically. On the fringes of the event, a car ploughed into a crowd of people in the so-called Tiergarten park. The Pride event was then called off. According to Dobrindt, the attack has been classified as an "Islamist terrorist attack".

As the minister explained in a statement at the scene at midday on Sunday, the suspected attacker not only used the van as a weapon, but is said to have gone after people with a machete afterwards. One woman was killed and 29 others injured. Dobrindt said he was "stunned and deeply shaken".
