TRIPOLI - The Libyan government on Tuesday firmly rebuffed a proposal by the European Union (EU), saying it would fight any foreign troops that landed on its soil, even if they were supposedly there to escort humanitarian aid convoys, according to state-run JANA news agency.

The EU has drawn up a "concept of operations" that could include sending European troops to the besieged Libyan city of Misrata to protect aid deliveries if approved by the United Nations, although UN officials said they want to explore civilian options first.

The situation in Misrata is worsening day by day as the city is surrounded on all sides by forces loyal to Libyan leader Muammar Gaddafi, who pummelled the city with rockets, artillery, shells and cluster bombs on daily basis.
