TUNIS, June 5 (Reuters) - Forces loyal to Libya'sinternationally recognised government said on Friday they hadentered Tarhouna, the last major stronghold of eastern commanderKhalifa Haftar near Tripoli, capping the sudden collapse of his14-month offensive.

There was no immediate comment from Haftar's Libyan NationalArmy (LNA) on whether its forces remained in the town, a dayafter they were pushed from their last positions in the capital.

Turkish backing has helped the internationally recognisedGovernment of National Accord (GNA) to a string of victories inrecent weeks, ending an assault on Tripoli that led to battlesin its southern suburbs and bombardment of the city centre.

The GNA operations room said in a statement that its forceshad reached the centre of Tarhouna after entering from foursides.

Abdelsalam Ahmed, a resident of Tarhouna, said GNA forceshad entered the town.

Libya's conflict is far from over, however, with the LNAstill controlling the country's east, where there is a paralleladministration, and large parts of the south, where thecountry's main oilfields are located.

The LNA is backed by Russia, the United Arab Emirates andEgypt.

The United Nations has warned that a recent flood of weaponsand fighters to both sides in Libya risks a major newescalation. urn:newsml:reuters.com:*:nL1N2D117C
