Hi Nuala here posting for Ros who is in Cairo as you've probably seen from his posts, pics and tweets. You can chat with him at 1700 & 1800GMT and we have three conversations that we'd like to take part in.

The fallout from the unrest in Syria appears to be intensifying. Across the border from Syria, a Turkish official said around one thousand Syrian refugees entered overnight, bringing the total to more than fifteen hundred since violence erupted in the Syrian town of Jisr al-Shughur earlier in the week. We'll bring you the latest at 1700 GMT. In the meantime, what's your reaction to this exodus of refugees?

Also, a US think-tank says hedge funds are behind "land grabs" in Africa to boost their profits in the food and biofuel sectors. It says the acquisitions have displaced millions of small farmers, and created insecurity in the global food system. However, some companies named in the report say that they're bringing more work, and higher salaries to impoverished areas. Is it harmful for hedge funds to buy up land in Africa?

And, Italian prime minister, Silvio Berlusconi,Battisti a former Italian left-wing militant and convicted murderer. Mr Berlusconi says his release denies justice to his victims. Italy says it will now ask the international court in the Hague to back its fight to get Mr Battisti returned. Is Brazil right not to extradite him? What do people in Brazil and Italy make of this case?

Whether it's Syrians in Turkey, "land grabs" in Africa or the Italian Cesare Battisti in Brazil that you'd like to talk about, please do get in touch.
