A Russian model-turned-Israeli lawmaker made a splash in Israel's parliament on Monday by dousing an Arab lawmaker with a glass of water after a spat during a committee hearing.

The unusual breach of protocol, even in the often-raucous Knesset, came after right-wing MP Anastassia Michaeli of the hardline Yisrael Beitenu traded barbs with Labor party lawmaker Ghaleb Majdale.

Israel is concerned Hizbullah will try to attack Israelis overseas in the coming weeks and ahead of the fourth anniversary of the assassination of the party’s military commander Imad Mughniyeh, The Jerusalem Post reported.

Mughniyeh was killed in a car bombing in Syria on Feb. 12, 2008. Hizbullah has accused Israel's intelligence service Mossad of assassinating him.

The prime minister in the Hamas-ruled Gaza Strip on Sunday promised "difficult days" for Israel, and at a rally in Tunis urged Arab Spring revolutionaries to fight for an independent Palestine.

Four Palestinian men were detained on Sunday after Israeli troops at a West Bank checkpoint discovered 12 pipe bombs, a knife and a gun in their possession, an Israeli police spokesman said.

The Israeli army believes that by 2017 Hizbullah and Hamas will have a huge number of missiles that can hit any area in Israel, The Jerusalem Post reported.

It said both groups could have “about 1,600 missiles with a level of accuracy of a few hundred meters and 800 with a level of accuracy of just a few dozen meters, giving them the ability to hit what they want.”

Israel said on Saturday that it will respond to cyber-attacks in the same way it responds to violent "terrorist" acts, by striking back with force against hackers who threaten the Jewish state.

The message from Deputy Foreign Minister Dany Ayalon came after a self-defined "Saudi hacker" from a cabal known as "group-xp" published details of more than 6,000 Israeli credit cards online.

Lebanon and Cyprus will hold talks to follow up discussions on demarcating the maritime border, As Safir newspaper reported on Friday.
