A twin bomb attack on police officers outside a football stadium in Turkey's largest city, Istanbul, has killed 38 people and injured many more. Police cordoned off the area around the stadium immediately after the blasts, which occurred near the Ottoman-era Dolmabahce Palace that houses Prime Minister Binali Yildirim's offices in Istanbul. Witnesses also heard gunfire after the explosions, which apparently targeted police officers, and at least 166 were reported wounded. Turkish President Recep Tayyip Erdogan, an ally to the United States in the fight against ISIS, issued a statement prior to the news conference saying Istanbul had once again "witnessed the ugliest face of terror stepping on all values and morals. The attack shook a soccer-mad nation still trying to recover from a series of deadly bombings this year in cities including Istanbul and the capital Ankara, some blamed on the Islamic State jihadist group and others claimed by Kurdish militants. Following the explosions, the US Consulate in Istanbul tweeted: "Please avoid the area, monitor local press reporting, and let friends and family know you are OK."

Erdogan declared a state of emergency following the coup attempt and authorities carried out a large number of arrests. "It is thought to be a car bomb at a point where our special forces police were located, right after the match at the exit where Bursaspor fans" had earlier left, Soylu was quoted as saying by Turkey's state-run Anadolu Agency. Twenty seven of those killed were policemen and two were civilians, he told reporters in Istanbul, adding that 10 suspects had already been detained over the bombing. It was followed 45 seconds later by another attack at nearby Macka Park, carried out by a suicide bomber who blew himself up in the midst of police officers. Deadly attacks in Turkey this year
