At least three people have been killed and seven more injured in fighting in the northern Libyan town of Bani Walid. The casualties come as clashes continue in the town of 85,000 residents, a former stronghold of ousted leader Muammar Gaddafi. Libyan soldiers have been fighting Gaddafi loyalists in the beseiged town for more than three weeks. But troops blame officials for not providing enough equipment or supplies to win the battle.
