Occupy Wall Street spreads abroad, video shows thugs sparked Egypt clashes, and more...

STORY 1: USA-IRELAND

We begin with the Occupy Wall Street movement. It began in a little park near Wall Street in New York. But it's now spread to cities across the US and in dozens of countries. The demonstrators are very diverse, and so are their demands - so it remains to be seen where the movement will go, and how long it will last. We talked to two of our Observers, in Boston and Dublin, and they say they're going to be camping out at least through the winter.

STORY 2: WORLD

Next up, a look at some of the images sent in this week by our Observers.

We begin in China with a story that's deeply shocked the nation. A 2 year old girl was hit by a van in a market in her hometown of Foshan. The driver of the van drove off without stopping. But it's what happens next that has the Chinese asking questions... Over the next seven minutes, 18 people pass the little girl's unconscious body and not one stops to check on her. Finally a trash collector pulls her out of the way. The girl, whose name was Yue Yue, has died, and the driver has been arrested. Our Observer Li Moral tells us that would-be good samaritans in China sometimes think twice before intervening because of a recent lawsuit. But even so, internet users are determined to identify and shame the 18 people who left her lying in the road.

Next stop Cairo, Egypt, where clashes that left 25 people dead on October. 9. It happened when security forces cracked down on a demonstration by Coptic Christians. But these pictures, shot by our Observer Mohammad Galal, show there were others involved - men in plain clothes, armed with knives, stones and bottles. They attack the demonstrators crying 'God is great'. Mohammad believes they are 'baltagiya' - thugs-for-hire who used to beat up opponents of the old regime. Hosni Mubarak may be out of the picture, but his bully boys are apparently still in the streets.

We finish today with a tribute to Steve Jobs from a one-year-old girl who has grown up in the age of the iPad and its tactile screen. So when she sees an old-fashioned magazine, she doesn't understand why it doesn't work, why the pictures don't move. Her dad explains that it's because Steve Jobs "has coded a part of her OS" - her operating system.
