JERUSALEM, Feb 11 (Reuters) - Israel hopes the resignation on Friday of Egyptian President Hosni Mubarak will bring no change to its peaceful relations with Cairo, a senior Israeli official said.

It's too early to foresee how (the resignation) will affect things, the official said. We hope that the change to democracy in Egypt will happen without violence and that the peace accord will remain.

There was no immediate comment from Israeli leaders at the start of the Jewish sabbath.

Egypt in 1979 became the first Arab country to sign a peace treaty with Israel and has backed US-led efforts to end the Israeli-Palestinian conflict.

Last week, Prime Minister Benjamin Netanyahu warned of an Iranian-style Islamist revolution in Egypt should Mubarak's Muslim Brotherhood rivals eventually take over.
