Libyan residents 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 has been a call for "concrete action" by Ban Ki-moon, the UN secretary-general. And its most powerful body will vote on fresh sanctions against Gaddafi and his entourage.

This after Gaddafi joined his supporters in the capital Tripoli - again vowing not to step down from office - and to fight to the end. Soon afterwards, protesters were fired upon in Tripoli, where another crackdown began after Friday prayers.

But just 50km away in the town of Zawiya, it was a different picture. Amateur video appeared to show more soldiers switching sides.
