An ISIS suicide bomber detonated his deadly explosive in a crowded, popular tourist area in Istanbul, Turkey Saturday, killing five people. Two of the victims were Americans.

According to numerous news sources, they held dual-citizenship with the United States and Israel.

“We have determined that Mehmet Ozturk, born in 1992 in Gaziantep, has carried out the heinous attack on Saturday in Istanbul. It has been established that he is a member of Daesh,” said Efkan Ala, Turkey’s Interior Minister.

Daesh is an alias of the Islamic State (ISIS, IS, ISIL, etc.).

Additionally, 36 other people were injured in the blast.

This from Reuters:

NATO-member Turkey is on heightened alert after the bombings, which have killed more than 80 people. A soccer match between Istanbul rivals Fenerbahce and Galatasaray was canceled on Sunday and the stadium evacuated on what appeared to be a security threat.

Israeli Prime Minister Benjamin Netanyahu has said Israel is trying to determine whether its citizens were deliberately targeted. Eleven of the 36 wounded were Israelis.

In his first public appearance since the bombing, President Tayyip Erdogan said Turkey would not give in to militants.

“We will never surrender to the agenda of terror. We will defeat the terrorist organizations and the powers behind them by looking after the unity of our nation,” he said.
