GAZA, Dec 8 (Reuters) - Hamas leader Khaled Meshaal, making his first ever visit to the Gaza Strip, vowed on Saturday never to recognise Israel and said his Islamist group would never abandon its claim to all Israeli territory.

"Palestine is ours from the river to the sea and from the south to the north. There will be no concession on an inch of the land," he told a sea of supporters at an open-air rally, the highlight of his three-day stay in Gaza.

"We will never recognise the legitimacy of the Israeli occupation and therefore there is no legitimacy for Israel, no matter how long it will take."
