Palestinian national security forces fired toward Israeli military vehicles in the northern West Bank on Tuesday, Palestinian security sources said.

There were no reports of injury in the incident, which came as military jeeps pulled up near the Palestinian security building at the northern entrance of Tulkarem, the sources said.

The governor of Tulkarem, Dalal Dweikat, denied any fire toward Israeli forces saying only that a Palestinian security officer misfired a single bullet in the same area as an Israeli patrol passed. "Things are calm and there are no developments," he said.

An Israeli military spokeswoman said the army was investigating the incident.

On Sunday, an Israeli settler was shot dead and four others were injured after a group of Jewish worshippers snuck into Nablus without coordinating with Palestinian or Israeli security.
