Libya conflict: Q&A

Tens of thousands of Libyans celebrate the arrest of Col Gaddafi's son, Saif al-Islam, and the partial fall of Tripoli into the hands of the Libyan rebels on 21 August 2011 in Benghazi, Libya

Libya's long-time leader Col Muammar Gaddafi has been killed in his home town of Sirte, officials say, by forces who have been trying to topple him since February, with the backing of Western and Arab nations.

Why did people want to oust Col Gaddafi?

Why did other countries intervene?

So was Nato backing the opposition?

Why did it take so long?

What happens now?

Where will the funds come from?
