Update Monday, December 13, 11:39 AM EST:
The twin blasts in Istanbul on Saturday ultimately killed 38 people and injured over 160 people, according to The Guardian.
On Saturday, Istanbul was rocked by dual explosions near a soccer stadium, and at least 20 people are wounded, Al Jazeera reports.
There are also reports that at least 13 people were killed.
Most of those killed or wounded were police officers, according to reports.
A car bomb was reportedly the source of the explosion.
Turkey has experienced a number of terror attacks in recent years.
In June, 47 people were killed in an attack at Istanbul's Ataturk Airport. The attack was blamed on ISIS.
Subsequently, in August, 57 people -- including 34 children -- were killed by an ISIS suicide bomber at a Kurdish wedding in the southeastern city of Gaziantep.
Turkey is also still recovering from a failed coup that occurred in July.
The exact moment of Saturday's explosion was caught on camera by terrified onlookers.

The startling explosion could also be heard on live TV.
Emergency vehicles have swarmed the scene of the explosion.
Omer Yilmaz, who witnessed the explosion, told Reuters,
It was like hell. The flames went all the way up to the sky. I was drinking tea at the cafe next to the mosque. People ducked under the tables, women began crying. Soccer fans drinking tea at the cafe sought shelter, it was horrible.
The interior ministry has called Saturday's incident a "terrorist attack," but it's not clear yet who is responsible.
ISIS has lost a large portion of territory and a significant number of fighters over the past year.
If it is responsible for the attack today, it could be a product of the fact the terrorist organization is getting increasingly desperate.
Turkey's involvement in Syria also makes it a target.
This is sadly yet another example of terrorism in a year where much of the globe has experienced far too much violence.
