Palestinian teachers held a strike Monday to demand the payment of long overdue salaries.
Hundreds of teachers tried to push their way into the West Bank offices of Education Minister Nasser Shaer and Prime Minister Ismail Haniyeh.
Police blocked the protesters. There were no reports of serious injuries.
The Palestinian government has been unable to pay full salaries to teachers and government workers for more than one year.
The United States and European Union suspended direct aid to the Palestinian government when the militant group Hamas won last year's parliamentary elections.
Earlier this year, Hamas formed a more moderate unity government with Palestinian President Mahmoud Abbas' Fatah movement in hopes of ending the Western aid embargo.
