Libyan rebel fighters say they have pushed back a counterattack by forces loyal to embattled ruler Muammar Gaddafi, Press TV reported.
The fighters say Gaddafi's forces attacked them again near the western town of Zlitan on Wednesday.
A similar counter attack on Tuesday left at least 7 revolutionaries dead.
The revolutionary forces have been inching closer to the key town in the past several days.
They have been pushing toward Zlitan from the port city of Misratah.
The revolutionaries hope to advance to the capital Tripoli from this town.
On Tuesday Gaddafi's son Saif al-Islam vowed that fighting will continue until Libya is liberated.
Libya has been the scene of intense fighting between government troops and revolutionary forces since mid-February.
The bloody conflict has left thousands of people dead and many others wounded.
Revolutionary forces want an end to Gaddafi's decades-long rule.
