Photograph: Jim Lo Scalzo/EPA Edward Helmore in New York Kaine attacks; Pence rolls with the punches Donald Trump was put on trial in his absence during the vice-presidential debate as his running mate, Mike Pence, was accused of trying to defend the indefensible. "Things don't always come out exactly the way he means," Pence said of Trump in a polished performance that may have given some hope to Republicans. But he was repeatedly forced on to the back foot by Democrat Tim Kaine, who presented him with a brutal catalogue of Trump's actions and words. "Six times tonight I have said to Governor Pence, I can't imagine how you defend your running mate's position," Kaine said. "He is asking everybody to vote for somebody that he cannot defend." But Kaine's relentless assault on Trump's record of contradictory or inflammatory statements, often interrupting or trying to talk over his debating rival, gave Pence the opportunity to deflect and deny.

The company apparently complied with a classified US government directive, scanning hundreds of millions of Yahoo Mail accounts. Surveillance experts said this represented the first known case of a US internet company agreeing to a spy agency's demand by searching all arriving messages. Reuters was unable to determine what data Yahoo may have handed over, if any. Yahoo 'secretly monitored emails on behalf of the US government' Hurricane Matthew heads for Florida coast The fiercest Caribbean storm in almost a decade has made landfall in Cuba after ripping through Haiti and the Dominican Republic, with at least seven people feared dead. The United States is now bracing for the storm's impact and a state of emergency has been declared in three US states – Florida, Georgia and South Carolina. Meanwhile, climate scientists warn that hurricanes will strengthen as global warming accelerates and sea levels rise. Hurricane Matthew makes landfall in Cuba after ripping through Haiti Three nanotechnologists win Nobel for chemistry A European trio of chemists have won the Nobel prize in chemistry for developing "nano-machines" that allow scientists to precisely manipulate materials on the molecular level. Sir Fraser Stoddart, from Scotland, Bernard Feringa, from the Netherlands, and Jean-Pierre Sauvage, from France, will share the prize for their design and synthesis of the "world's smallest machines" which could in future pave the way for medical "micro-robots" and smart materials. 'Nano-machines' win European trio chemistry Nobel prize Extreme poverty worsens Nearly half of all children in sub-Saharan Africa are living in extreme poverty, according to a joint Unicef-World Bank report, with figures showing that almost 385 million children worldwide survive on less than $1.90 a day, the World Bank international poverty line. Children are disproportionately affected by extreme poverty – they make up just a third of the population studied, but comprise half of the extreme poor.

Hollywood's top entertainment lawyer, fresh from a $140m lawsuit against Gawker on behalf of Terry Bollea, AKA Hulk Hogan, is representing Melania Trump, potential first lady of the United States, in a $150m lawsuit against the UK's Daily Mail, just months before the presidential election. "The takeaway is that news organizations need to be responsible, just like lawyers, doctors, and teachers," he tells the Guardian.

But councilwoman Bethany Tjornhom warned that the city needed to consider whether it wanted to be a "tourist town", hosting upward of 600,000 visitors annually.

The film is said to use Lee's notorious private fight with Wong Jack Man as the starting point for a mafia thriller and actually focuses on a fictional white friend, Steve McKee, who learns kung fu and romances a Chinese woman.
