A fire broke out in Turkey's capital city of Ankara Tuesday with initial reports indicating a large explosion, but Twitter reports later suggesting it was a fire in a large residential building.

The report emerged less than a week after a failed coup in Turkey reportedly left more than 200 people dead. The government arrested dozens of military officials were and fired thousands of workers.

The state-run Anadolu news agency reported those formally arrested included former air force commander Gen. Akin Ozturk, alleged to be the ringleader of the July 15 uprising, and Gen. Adem Hududi, commander of Turkey's 2nd Army, which is in charge of countering possible threats to Turkey from Syria, Iran and Iraq.

Ozturk has denied the allegation, saying he neither planned nor directed the failed military coup.

The news agency said Erdogan's Air Force adviser, Lt. Col. Erkan Kivrak, had been detained at a hotel where he was vacationing in Turkey's southern province of Antalya. No reason was given for the detention.

Addressing hundreds of supporters outside his Istanbul residence early Tuesday, Turkish President Recep Tayyip Erdogan responded to calls for the reintroduction of the death penalty with the simple statement: "You cannot put aside the people's demands."

"In a country where our youths are killed with tanks and bombs, if we stay silent, as political people we will be held responsible in the afterlife," Erdogan said, pointing out that capital punishment exists around the world, including in the United States and China.

Anadolu also reported Tuesday that Turkey's media regulatory agency canceled all broadcast rights and licenses for any media outlets linked to or supporting the group the government holds responsible for Friday night's failed coup.
