The UN Security Council unanimously adopted a resolution Saturday imposing sanctions on Libya, including an arms embargo against the country and a travel ban and asset freeze against Libyan leader Muammar Gaddafi and his key family members.

The Security Council also expressed "grave concern" at the current situation in Libya, and called for "an immediate end to the violence and for steps to address the legitimate demands of the population" in the North African country.

The Security Council decides that "all member states shall immediately take the necessary measures to prevent the direct or indirect supply, sale or transfer to the Libyan Arab Jamahiriya ... of arms and related material of all types, including weapons and ammunition, military vehicles and equipment, paramilitary equipment, and spare parts," the resolution said.

The travel ban is to be imposed on Gaddafi, his key family members, including Gaddafi's son Saif al-Islam, and high-ranking officials of the Tripoli regime, the resolution said.

The Security Council "decides that all member states shall freeze without delay all funds, other financial assets and economic resources which are on their territories, which are owned or controlled, directly or indirectly," by the listed individuals or entities of Libya, the resolution said.

"Member states shall ensure that any funds, financial assets or economic resources are prevented from being made available by their nationals or by any individuals or entities within their territories," the resolution said.
