Top US defense military official has said that the Islamic State group presented a long term threat greater than any other so far, and needed to be defeated in Syria, as well as Iraq. Both US Defense Secretary Chuck Hagel and his Chief of Staff Martin Dempsey were speaking after the grisly murder of an American hostage by the group. From Washington, here is Barbara Plett Usher.

“General Dempsey said it was possible to contain the Islamic State militants for a time, but they would eventually have to be defeated. That couldn't be done without addressing their base in Syria and without the help of a regional coalition, he said. Neither he nor Secretary Hagel announced new military steps beyond the limited air strikes authorized by President Obama. But both described the threat in stark language. Short term, for westerners fighting with the Islamists, it might return home. Long term, said Mr. Hagel,Islamic State demonstrated a combination of sophistication, money, resources and tactical ability beyond any terrorist threat so far seen. 'We need to prepare for anything,' he said.”

A hospital in the United States has discharged two American missionaries who has been treating the Ebola virus, saying they pose no risk to public health.

Bank of America has agreed to pay almost 17 billion dollars for selling toxic mortgage loans that helped trigger the financial crisis in 2008. The bank was accused of misleading investors into buying mortgage-backed securities that the soldiers saved for investments and led to billions of dollars of losses. The US Attorney General Eric Holder said it was the largest deal the Justice Department has ever reached with a bank.

I want to be very clear, the size and the scope of this multi-billion-dollar agreement goes far beyond the cost of doing business. This outcome does not preclude any criminal charges against the bank or its employees, nor was it inevitable. Over these last few weeks, this case would have been resolved out of court.

Turkey's governing AK Party has nominated the Foreign Minister Ahmet Davutoglu as the country's next Prime Minister. The decision was announced by the outgoing prime minister Recep Tayyip Erdogan who takes over as President later this month. Sallen Garage reports.

Mr. Davutoglu was not the obvious choice for the post of Prime Minister. Initially the strongest candidate for the position was thought to be the outgoing President Abdullah Gul, but his name was soon discounted. Mr. Davutoglu has been loyal to Mr. Erdogan first as an adviser and then as Foreign Minister. He will become Prime Minister after his election as the governing party's new leader at the Congress next week. The opposition suspects he will run the government at the bidding of Mr. Erdogan and says Turkey is heading to a new era of puppet Prime Ministers.
