Hamas supporters raised their flag over the Palestinian parliament Thursday and rushed into the building amid clashes with Fatah loyalists a day after winning parliamentary elections.

The two camps threw stones at each other, breaking windows in the building, as Fatah supporters briefly tried to lower the green Hamas banners. The crowd of about 3,000 Hamas backers cheered and whistled as activists on the roof of the parliament raised the Hamas banner again.

It was the first confrontation between Hamas and Fatah since the Islamic militant group won parliamentary elections on Wednesday.
