Forces loyal to Muammar Gaddafi crossed into neighboring Tunisia and fought a gun battle with Tunisian troops in a frontier town as Libya's conflict split beyond its borders.
Pro-Gaddafi forces fired shells into the town of Dehiba, damaging buildings and injuring at least one resident, and a group of them drove into the town in a truck, local people and a Reuters photographer in the town said.
The Libyan government troops were pursuing anti-Gaddafi rebels from the restive Western Mountains region of Libya who fled into Tunisia in the past few days after Gaddafi forces overran the border post the rebels had earlier seized.
"There were lots of clashes in the town this morning. Lots of gunshots. The Tunisian military clashed with Gaddafi's forces ... Some of Gaddafi's people were killed," said Reuters photographer Zoubeir Souissi from the town.
"There are a lot of Gaddafi's people who were injured. They are in the hospital in Dehiba," he said.
Two residents also told Reuters that shells had fallen on the town from pro-Gaddafi positions across the border in Libya.
