Two U.S. officials said Wednesday there are no indications that the massive explosion Tuesday evening in Lebanon's capital was the result of an attack by either a nation state or proxy forces.

A senior Defense Department official and a member of the U.S. intelligence community told The Associated Press that, at the moment, the explosion appears to have been caused by improper storage of explosives.

Turkey said Wednesday it is sending search and rescue teams along with emergency medical personnel to aid Lebanese authorities in the aftermath of the devastating explosion that killed at least 100 people in Beirut and injured thousands.

Foreign Ministry spokesman Hami Aksoy said a field hospital was also in the works, adding that Turkey was sending humanitarian aid, medical equipment and medicine to Beirut.

The World Health Organization says it is airlifting medical supplies to Lebanon to cover up to 1,000 trauma interventions and up to 1,000 surgical interventions following the explosion in Beirut.

Russia's emergency officials say the country will send five planeloads of aid to Beirut after an explosion in the Lebanese capital's port killed at least 100 people and injured thousands on Tuesday.

President Donald Trump said U.S. military generals have told him that they "seem to feel" the massive explosion that rocked Beirut on Tuesday, killing at least 70 people, was a "terrible attack" likely caused by a bomb.

Trump was asked why he called it an attack and not an accident, especially since Lebanese officials say they have not determined the cause of the explosion. He told reporters at the White House: "It would seem like it based on the explosion. I met with some of our great generals and they just seem to feel that it was. This was not a — some kind of a manufacturing explosion type of a event. ... They seem to think it was a attack. It was a bomb of some kind, yes."

A massive explosion rocked Beirut on Tuesday, flattening much of the port, damaging buildings across the capital and sending a giant mushroom cloud into the sky. At least 50 people were killed and 2,700 injured, with bodies buried in the rubble, officials said.

Hours later, ambulances still carried away the wounded as army helicopters helped battle fires raging at the port.
