The latest airstrikes come as the rebel National Transitional Council, the NTC, agreed to open a representative office in Washington.
Speaking from the rebel held city of Benghazi, Jeffrey Feltman, the US Assistant Secretary of State of Near Eastern Affairs, said President Obama had invited the Council to establish a representative office in the US capital.
“There is an ongoing diplomatic, political relationship and dialogue with members of the council who are considered by our fellows credible and legitimate representatives of the Libyan people,” he said.
Britain, France, Gambia, Italy and Qatar have already recognised the rebel council as their sole interlocutor in Libya.
Feltman also announced the US was granting the Libya opposition 53.5 million dollars in aid for humanitarian needs, including 25 million for non-lethal military supplies.
Meanwhile, forces fighting Kadhafi have received a boost after Britain said it would provide attack helicopters along with France for Nato’s air campaign and the European Union announced it was widening s against Kadhafi’s troops.
The attack helicopters have not yet been used in Libya and aim to help Nato strike military assets hidden in urban areas while avoiding civilian casualties.
And the EU assets freeze and travel ban against Kadhafi loyalists and firms suspected of propping up the regime has been extended to members of the Libyan leader’s inner circle and a Libyan airline.
