The US House of Representatives has sent President Barack Obama a strong rejection on any further US military action in Libya.
The United States has conducted hundreds of strikes over Libya since NATO took over the Libya operation on March 31st.
Friday's congressional action showed the growing discontent among US lawmakers over US-sanctioned wars, which have been going on in Afghanistan and Iraq for over a decade, costing more than a trillion dollars.
With a $1.4 trillion budget deficit to contend with, the legislators defeated the Obama measure on Friday with 295 votes against and only 123 votes in favour.
Democratic Representative Dennis Kucinich said during Friday’s vote: "This war is a distraction. Our flailing economy demands the full attention of Congress and the president."
NATO Secretary General Anders Fogh Rasmussen had been asking for the US and other countries to intensify bombing missions in Libya.
Meanwhile, embattled Libyan ruler Muammar Gaddafi has accused NATO of murder, vowing to retaliate for the killing of civilians during air raids.
Gaddafi has said the battle will continue until the West is “wiped out.”
