Reports say it's not clear what is happening, but that police were apparently upset by the election victory on 25 January by the Hamas militant group.
In Israel today, acting Prime Minister Ehud Olmert said Israel would freeze payments to the Palestinian Authority, following Hamas's win. Hamas is opposed to the state of Israel, and Olmert today said it must be made clear that Israel would not provide funds that could finance terrorist attacks.
In London, representatives of the so-called Middle East quartet -- the European Union, the United Nations, the United States, and Russia -- is meeting to discuss how to deal with a Palestinian government led by Hamas.
The quartet is to discuss possibly isolating Hamas to persuade it to recognize Israel and drop calls for Israel's destruction from the group's charter.
