US President Obama has delivered a tough warning to Libyan leader Muammar Gaddafi. (See full text here).
These are extracts:
"All attacks against civilians must stop. Gaddafi must stop his troops from advancing on Benghazi, pull them back from Ajdabiya, Misrata and Zawiya, and establish water, electricity and gas supplies to all areas.
"Humanitarian assistance must be allowed to reach the people of Libya.
"Let me be clear, these terms are not negotiable.
If Gaddafi does not comply, the international community will impose consequences, and the resolution will be enforced through military action.
"Our goal is focused, our cause is just and our coalition is strong."
