Israeli tanks advanced briefly into the Gaza Strip following clashes with Palestinians in which two Israeli soldiers died, reports say.

Witnesses in Gaza said tanks and bulldozers moved towards the southern town of Khan Younis before withdrawing.

They also said there had been firing from the Israeli navy along the Gaza coastline.

It is the first time Israeli soldiers have died in Gaza since Israel's 22-day offensive there more than a year ago.

Reports say at least two Palestinians have also been killed.
