US Defense Secretary Mark Esper on Wednesday contradicted President Donald Trump's earlier claim as to the cause of the explosion in Beirut, Lebanon.<br />CNN reports Esper said 'most believe' that the explosion 'was an accident, as reported.'<br />On Tuesday evening, Trump called it 'a terrible attack.'<br />It's known that about 2,750 metric tons of ammonium nitrate had been stored at a port warehouse for the past six years.<br />It's also known that the highly explosive material was stored 'without preventive measures.'<br />The deadly explosion has claimed at least 135 lives, including one US citizen, and injured thousands.<br />I will not rest until we find those responsible for what happened, hold them accountable, and impose maximum punishment. Lebanese Prime Minister Hassan Diab
