The Syrian government's representative Bashar al-Jaafari blamed the opposition for the disruption. The United Nations has called a temporary halt to talks aimed at ending the war in Syria. The UN envoy Staffan de Mistura insisted the effort to negotiate a settlement in Geneva hadn't failed and would resume on February 25, but he said more work needed to be done. One of the Syrian opposition negotiators Basma Kodmani criticized what she called the heavy airstrikes that Russia had launched even as the talks were meant to be taking place, and said there needed to be a more robust response.

"We were confident because we had received written assurances from Washington that’s coming to Geneva was a meaningful that the hope was there, that there was enough hope for us to come over and really engage in good faith. That is really what happened. And we are very very surprised that today we only have statements in response. We hope to see something more than that." The Syrian government's representative blamed the opposition for the disruption.

France has accused President Assad and his allies including Russia of torpedoing the Syrian peace talks. The United States has also criticized Russia saying its airstrikes against civilian targets were hindering the peace process. The US State Department's spokesman is John Kirby.

The German Chancellor Angela Merkel has pressed the start button on an experimental reactor designed to create clean energy through nuclear fusion. A small amount of hydrogen gas was held in a magnetic cage and superheated with microwaves. For a fraction of a second, the gas transformed into plasma at a temperature of 80 million degrees Celsius. Professor David Anderson said putting the theory of replicating the power of the stars into practice to create limitless energy is the greatest challenge.

"We know the fusion process works. We have stars in the sky. We have generated fusion energy in two experiments to date, so we really need to move now into a situation where we can try to take the scientific advances and push them into more of a practical application."

The case will now move to a preliminary hearing in which prosecutors will have to demonstrate that they have enough evidence. Bill Cosby is accused of assaulting the woman at his home in 2004.
