Security forces in Tunisia have been fighting a gun battle with suspected members of the presidential guard at the presidential palace, several kilometres north of the capital Tunis. The Tunisian Prime Minister Mohamed Ghannouchi told national television that there'd be zero tolerance for anybody who'd threatened the country's security following the overthrow of President Zine El Abidine Ben Ali last Friday. Mr Ghannouchi has said a new coalition government could be announced on Monday. With more on the day's events, here's Wyre Davies.

It appears that small groups of armed men perhaps loyal to the former president are trying to disrupt this very slow process of change. All of this happening of course while the interim president has been trying to convene other interested political parties to form his government of national unity and hopefully pave the way for national elections, but it's not a smooth process. There have been attacks, not by the army - I think that's a crucial thing - the people perhaps who are, perhaps are to be more sinister as some of the security services that supported the former president.

The leader of the militant Lebanese group Hezbollah says his movement will reject any indictments from a UN tribunal that's investigating the murder in 2005 of the country's former Prime Minister Rafik Hariri. In his first public comments since the Lebanese government collapsed last week, Sheikh Hassan Nasrallah accused the tribunal of being highly politicised. From Beirut, here's Owen Bennett Jones.
