From Our Own Correspondent

Weeks of violent confrontation in Uganda: Will Ross is in Kampala where lawyers are the latest group to protest against the regime of President Museveni. Mishal Husain is in the Pakistani town of Abottabad, where the life of Osama bin Laden, the world's most wanted man, was brought to an end last Sunday. Mishal talks of the new interest in this location which she remembers as a place her family went on holiday. President Obama was at Ground Zero this week and coincidentally, a little earlier, our correspondent Paul Adams was there with his two young sons who had awkward questions to ask about that day when the Twin Towers came crashing down. There's a new predator in the Caribbean -- the Lionfish. Tim Ecott's been to the Cayman Islands to get an idea of the scale of the problem it's brought with it. And Jonathan Fryer waits and waits for the night bus to Bolivia. But at least he has some company in the shape of a large, and affectionate, wild pig!
