* Some projectiles appear to land inside Tunisia
* Rebels had held border crossing since last week
(Adds details from border)
DEHIBA, Tunisia, April 28 (Reuters) - Forces loyal to Libyan leader Muammar Gaddafi shelled rebel positions on Thursday around a border crossing with Tunisia that the insurgents captured last week.
A Reuters cameraman in the border area said some of the rounds appeared to have landed on the Tunisian side.
Rebel fighters from the restive Western Mountains region of Libya took control of the border crossing last week and since then expanded the area under their control to reach about 10 km (six miles) inside Libyan territory.
But they had expected a counter attack.
A Tunisian man at the Dehiba-Wazin border crossing told Reuters earlier that travellers and Tunisian border officials were leaving the checkpoint in anticipation of the arrival of pro-Gaddafi forces.
Reuters cameraman Abdelaziz Boumzar said many of the rebel fighters who had been at the crossing headed up towards the front line and the Libyan town of Wazin before the shelling began. (Reporting by Zoubeir Soussi in Dehiba and Tarek Amara in Tunis; Editing by Matthew Tostevin)
