In Israel, the question of rocket fire from Gaza remains an issue in campaigning ahead of the country's legislative elections on Tuesday. Former President Benjamin Netanyahu, on Sunday vowed to eradicate rocket fire as well as arms smuggling into Gaza.
Netanyahu's right-wing Likud party is considered favourite for the vote although 20 per cent of voters have told surveys they are undecided.
The leader of the centrist Kadima party, Foreign Minister Tzipi Livni, has said she is "not associated" with suggestions by outgoing Prime Minister Ehud Olmert to remove settlers from the West Bank and to give Palestinians some control of Jerusalem.
The last polls before Tuesday's snap election, gave Likud 25 to 27 seats and Kadima 23 to 25 seats. Israel's traditionally left-wing party, Labour could, if the opinion pollsters' forecasts are right, be relegated to the country's fourth most important party. The ultra-nationalist Yisrael Beitenu party, they predict, could garner up to 19 seats out of the 120 in the Knesset - Israeli's parliament.
