GAZA (Reuters) - The Gaza-based Islamist group Hamas and President Mahmoud Abbas's Palestine Liberation Organization (PLO) agreed on Wednesday to implement a unity pact, both sides announced in a joint news conference.

The move envisions forming a unity government within five weeks and holding national elections six months after a vote of confidence by the Palestinian parliament.
