Almost ten years of talks, aimed at bridging the differences between Hamas and Fatah, have had little success.
Representatives of the two groups are meeting yet again, this time in Qatar, to try and resolve their differences.
The two have been at odds since 2006, when Hamas won parliamentary elections. It then forcibly took control of Gaza in June 2007, after battling with security units loyal to Fatah.
Now, however, political expediency might just bring the two together to present a united front against Israeli occupation.
But what are the chances of success this time around? And can they work together?
