Gunmen opened fire on Sunday at a bus of Israeli soldiers that was traveling near the Israel-Egypt border.
The bus was hit when it was on Route 10 near Har Sagi, southwest of Mitzpe Ramon. No casualties were reported but damage was done to the bus.
IDF forces were called to the area.
Last week, Israeli troops shot dead one unarmed man, and wounded another who were trying to cross into Israel from Egypt.
Last month, a terrorist cell crossed the border from Egypt into Israel and detonated an explosive device which ended up killing an Israeli citizen who was working on the construction of the Israel-Egypt border fence, sparking an escalation in the south.
Hundreds of rockets were fired into southern Israel and IDF carried out numerous strikes in the Gaza Strip.
On August 18 last year, eight Israelis were killed on a desert border road near Eilat by gunmen who Israel said infiltrated from the Gaza Strip via Egypt's neighboring Sinai desert. Seven of the attackers were killed by Israeli forces and Egypt said five of its men died in the crossfire. The incident triggered a serious diplomatic row between the two countries.
