According to a preliminary Israeli army investigation, some 20 youths were hiking in the Qusra area accompanied by an adult, when they were surrounded by dozens of Palestinians who began to hurl rocks at the group.
But the Israeli military claims that Odeh was shot after "throwing stones" and "lightly wounding two settlers", during the confrontation.
Mohammad Amireh, a local anti-settlement activist, said that Palestinians performed Friday prayers in their olive groves, south of the village, expressing their condemnation of the killing of a Palestinian farmer by Israeli Jewish settlers in Nablus-district village of Qusra.
The Israeli military said the shooter had opened fire in self-defence as part of a group of settlers hiking near the village of Qusrah who had come under attack.
Israeli medics treated him at the scene, but he died from his wounds.
"The critical situation resulting from the air, land and sea blockade presupposes the nearly total isolation and great deprivation of the 2 million Palestinian civilians living in the area", the Cuban ambassador said.
Ghassan Daghlas told the Associated Press that Mr Odeh had been at work when a group of settlers trespassed onto his land and then ordered him to move. "IDF forces arrived at the site and rescued all the hikers".
Palestinian reports said Odeh was working in his field when the hikers arrived. Israel says majority were attackers and that others died in clashes with Israeli forces.
More than 600,000 Jews live in about 140 settlements built since Israel's 1967 occupation of the West Bank and East Jerusalem.
