Palestinians bomb Hamas targets in Gaza

GAZA (Reuters) - Palestinian gunmen set off two bombs in Gaza City on Tuesday at separate locations belonging to forces of the Islamist group Hamas, causing damage but no casualties, local security officials said.

No group claimed responsibility for the simultaneous explosions, and an Israeli army spokesman ruled out any Israeli involvement.

Attacks on Hamas have been relatively rare since it seized control of the coastal Gaza Strip after a bloody battle with Palestinian President Mahmoud Abbas's secular Fatah faction in June.

Earlier on Tuesday, a Hamas policeman and eight armed members of a Gaza clan were wounded in a clash in the town of Khan Younis.

When members of the Hamas Executive Force tried to arrest a clan member, other clansmen opened fire and threw pipe bombs at the Hamas force, who fought back.
