Nation: More than 5,000 people have been evacuated near Marysville outside Knoxville, Tennessee after a train carrying toxic chemicals derailed Wednesday at midnight and caught fire. At least 25-people were admitted to a local hospital with respiratory issues. The train was carrying a flammable, toxic chemical called acrylonitrile and authorities cleared residents for a two mile radius to protect them from breathing toxic fumes.

The Joblot: Unemployment fell to 5.3 percent in June, a 7-year low, with the addition of 223,000 jobs to the economy. On the downside, wages are not growing and fewer people are looking for work, an indication that many have given up and it’s still tough out there. The news may convince the Federal reserve to hold off raising interest rates until later in the year.

Permawar: Syrian rebels cooperating with Islamist groups have begun a full scale attack on the northern city of Aleppo, showering it with rockets. Aleppo, which is Syria’s largest city and its industrial center, has been embattled since the civil war began in 2012.

The Greek Thing: Sunday’s vote on a financial bailout for Greece is turning into a referendum on the leadership of Prime Minister Alexis Tsipras. His political opponents are pushing Greeks to vote “yes,” which would be a huge defeat for Tsipras and a signal that he’s got to go. A poll by Ethnos newspaper shows voters split, with the “Yes” vote at 44.8% and “No” at 43.4%. In the same poll 74% want to stay with the euro, which means they would have to vote against Tsipras.

Oily Residue: The British oil company BP has agreed to pay $18.7 billion in fines to the federal government and Gulf states for the 2010 Deepwater Horizon oil rig spill. It’s the largest environmental settlement in US history. The company has already spent $4 billion on criminal fines and $14 billion on cleanup. The whole disaster could end up costing BP $40 billion.

The Gathering Crowd: Former US Sen. James Webb of Virginia, a Marine veteran of Vietnam and a novelist, yesterday declared himself a Democratic candidate for president. It’s a longshot. “I understand the odds, particularly in today’s political climate where fair debate is so often drowned out by huge sums of money,” Webb said in a statement.

Speaking of money, socialist candidate Bernie Sanders has shown a surprising ability to raise it. Sanders won’t take money from big donors but he still brought in $15 million in the last two months. Of course that’s against $45 million in three months for Hillary Clinton, who’s expected to bank $1 billion for her campaign.

Church Fires: Investigators say the cause of a fire that burned a predominantly black church in Greeleyville, South Carolina does not appear to have been arson. They suggest it may have been bad weather, but the cause has not been pinned down. Several other black churches that have burned in the South in recent weeks were deliberately set on fire.

Flight: The solar-powered airplane Solar Impulse is expected to land within hours this morning in Hawaii after making the flight from Nagoya, Japan. The Pacific crossing has been one of the diciest legs of the plane’s round the world journey powered only by the sun.

Laugh In: During a symposium with Goldie Hawn at the Aspen Ideas Festival former Disney boss Michael Eisner said, “the hardest artist to find is a beautiful, funny woman.” Well, there’s Tina Fey, Kristen Wiig, Parker Posey, Leslie Mann. So you have to sympathize with Eisner. It’s harder for entertainment executives who have no sense of humor themselves.
