(From L to R) Palestinian legislator Mustafa Barghouti, Palestinian Fatah delegation chief Azzam al-Ahmed, Hamas prime minister in the Gaza Strip Ismail Haniya, secretary-general of the Palestinian Arab Front (PAF) Jameel Shehadeh and Hamas deputy leader Musa Abu Marzuk clap as they celebrate in Gaza City on April 23, 2014 after West Bank and Gaza Strip leaders agreed to form a unity government within five weeks as peace talks with Israel face collapse. Under the rapprochement between the Palestine Liberation Organisation (PLO) -- internationally recognised as the sole representative of the Palestinian people -- and the Islamist Hamas which rules Gaza, the sides agreed to form a "national consensus" government within weeks.
