Protests continue in Libya

In Libya people are waking up to a twelfth day of turmoil.

But longtime ruler Muammar Gaddafi and his son Saif al-Islam say they are going nowhere.

Despite growing support for anti-government demonstrators, both at home and abroad, there's been a call for "concrete action" by Ban Ki-moon, the UN secretary-general.

And its most powerful body votes on fresh sanctions against Gaddafi and his entourage.

This after the Libyan leader joined his supporters in the capital - again vowing not to step down from office - and to fight to the end.

And these are the implications - protesters fired upon in Tripoli, where another crackdown began after Friday prayers. We'll hear from someone who was there.

But just 50km away in the town of Zawiya there is a different picture. Amateur video appears to show more soldiers switching sides.
