The parents of an Israeli soldier detained in Gaza have urged Israel to hold Mahmud Abbas's Palestinian Authority responsible for his fate in the wake of a unity deal between rival groups Fatah and Hamas.
In a letter to Prime Minister Benjamin Netanyahu, Gilad Shalit's parents called on his government to impose punitive measures against the Fatah-dominated PA to secure their son's release.
"The Israeli government must meet to decide on the measures to be undertaken against the Palestinian Authority on the issue of Gilad Shalit," their letter reads.
"Israel must make clear to them that after the signing of the reconciliation accord, it considers them bound to apply the Geneva Convention" on the treatment of prisoners of war.
Parents Aviva and Noam Shalit also urged the government to suspend the transfer of Palestinian tax revenue to the PA, a move which the finance minister has said he will take following the unity deal which Israel has condemned.
Shlomit Almog, a lawyer for the Shalit family, told AFP they intended to raise the issue of the transfer of Palestinian funds before the supreme court.
Gilad Shalit, now 24, was seized in a dawn cross-border raid in 2006 by three groups of Gaza militants including Hamas, the Islamist movement which rules the Palestinian territory.
Hamas has demanded Israel's release of hundreds of Palestinian prisoners in exchange for Shalit's freedom.
