The meeting between motivational speaker Brad Burton and Sam Wall lasted less than a minute. She posed for a picture with him after attending one of his workshops and later left a glowing video testimonial.

It was unremarkable, Mr Burton says. "Just one of the thousands of people I must have met over the years."

Two years later, she started attacking him online.

In hundreds of posts, Wall described him as manipulative, a psychopath and a sociopathic abuser. Day after day, she accused him of making death threats, breaking her windows and killing her cat - all false allegations.

"She put it on social media across all platforms. She was painting a picture that, somewhere along the way, I had done all these things and I was trying to cover it up," Mr Burton tells BBC Panorama.

"How do you prove a negative? That I had not poisoned the cat? Social media and the way it works, it's guilty until proven innocent."

Nine Palestinians have been killed and 35 injured by Israeli forces during a major operation in Jenin in the occupied West Bank, the Palestinian health ministry says.

Palestinian media reported that there were a series of air strikes as a large number of troops moved in to the city and its refugee camp, backed by drones, helicopters and armoured bulldozers.

Israel's prime minister said it launched an "extensive and significant" operation to "defeat terrorism" in Jenin, long seen as a stronghold of Palestinian armed groups.

It comes three days after the start of a ceasefire in Gaza and highlights the threat of more violence in the West Bank, where suspected Israeli settlers also went on the rampage overnight.
