The US Defense Secretary Ash Carter says American special forces will be deployed to Iraq to help fight Islamic State militants in both Iraq and Syria. Mr. Carter said the troops would be able to carry out raids, free hostages and capture IS leaders. American special operators bring in a unique suite of capabilities that make them force mobile fliers. They will help us garner valuable ground intelligence, further enhance our air campaign, and above all enable local forces that can regain and then hold territory occupied by ISIL. Where we find further opportunity to leverage such capability, we are prepared to expand it. Our Washington correspondent Gary O'Donoghue has more on the role of the US forces. A rather vivid phrase that Ash Carter used in his testimony to Congress this morning, he said he wanted Islamic State fighters to wonder who is gonna come in through the window during the night. And so that there will be extra special forces possibly in Syria, certainly in Iraq. They will conduct raids. They will try to kill ISIS leaders. They will try rescue hostages. And this is all recognition, I think, that the US feels it has to intensify the battle against Islamic State, that the air war is not enough. And it is calling on its coalition allies to do the same.

Hundreds of scientists have gathered in Washington for an international summit on gene editing. The Nobel Laureate David Baltimore said the delegates must consider what he called the deep and disturbing questions raised by the new technology. From Washington, here's Fergus Walsh. It's just three years since a new, cheap and easy form of gene editing was discovered and already labs across the world have adopted it. It raises the hope that patients with muscle, blood or immune disorders could have their faulty tissue removed, treated in the lab and then healthy cells re-infused. But if gene editing was done in embryos, then any DNA changes would pass down the generations. That might allow a permanent fix for some genetic diseases. World news from the BBC.
