Britain called for an international probe into the "atrocities" taking place in Libya Thursday as Prime Minister David Cameron said leader Muammer Gaddafi 's behaviour could not be allowed to stand.
Cameron said Gaddafi’s violent attempts to cling to power were "utterly unacceptable" as Foreign Secretary William Hague said the world would be looking for ways to hold to account those responsible.
"The behaviour of this dictator cannot be allowed to stand," Cameron told BBC television in the Omani capital Muscat, where he is wrapping up a tour of Gulf States.
"What is happening in Libya, the violence meted out to his own people, is a completely unacceptable way to behave and consequences should follow from that behaviour."
He stressed that he had never supported Gaddafi or his regime and said he did not oppose further sanctions.
"I think Britain, with her allies, should be looking at all of the options for the future," he said.
He added that "The international community needs to speak strongly and with one voice and so far the signs are good."
Asked whether he thought Gaddafi was sane, he said he did not need to be a doctor to see that the Libyan leader's actions were not acceptable.
Hague told BBC radio the world was shocked by the behaviour of Gaddafi’s regime.
"We've got the remnant of a government that is prepared to use force and violence against its own people," he said.
He added that “atrocities" have taken place in reference to attempts the bombings and shootings of their own countrymen.
"The most immediate thing that we want them to understand is that we will be looking for ways to hold to account the people who are responsible for these things and they should bear that in mind before they order any more of them."
Hague also emphasised "Certainly we will want some kind of international investigation. In order to bring that about we have to persuade other countries."
