What we know about the Philippine resort attack and how it unfolded

— -- At least 35 people died at Resorts World Manila in the Philippines after a gunman stormed the resort in an attempted robbery and torched gambling tables, creating a choking amount of smoke, law enforcement and company officials said.

The dead included at least 13 employees and 22 guests, authorities said. Police told ABC News the initial investigation indicated that the victims, who were found mostly on two floors, died from smoke inhalation in the incident, which occurred early Friday local time. The Associated Press reported that the Foreign Ministry said one person died of a possible heart attack during the evacuation.

In addition to those who died, more than 70 people suffered mostly minor injuries in the stampede to escape, according to the AP.

Stephen Reilly, Resort World's Chief Operating Officer, says the company is giving 1 million pesos ($20,000) to each of the families of those who died, according to The AP. "Yesterday we lost so many lives because of this senseless act," he said Saturday. "We hope that we will be able to somehow help."

The gunman attempted to flee with casino gambling chips and went to a room in an adjoining hotel where he holed himself up before taking his own life, Resorts World COO Stephen Reilly said in a press conference.

Photos obtained by ABC News show the interior of the resort in the aftermath of the attack.
