Gunfire broke out at Gaza's border crossing with Egypt as Palestinian Authority Prime Minister Ismail Haniyeh left the area for reconciliation talks between his Hamas movement and the rival Fatah group, officials at the border said.
Haniyeh crossed into Egypt unharmed, the officials said.
Fatah officials policing the border said they had fired in the air to disperse a large crowd of people trying to push through the crossing after Haniyeh.
The crossing - Gaza's gateway to the outside world - has been closed to outgoing traffic since January 8 because of Israeli security alerts. It was briefly opened Tuesday to allow Haniyeh to pass through to Egypt.
