Israel minister accuses Abbas of stirring new war with Hamas

Israel's defence minister on Thursday accused the Palestinian president of trying to spark a fresh conflict between the state and Abbas's longtime rivals Hamas in Gaza.

Avigdor Lieberman said Mahmoud Abbas, the head of the Fatah movement that rules the occupied West Bank, was trying to increase tensions by cutting payments for electricity and other services in Gaza.

"Abu Mazen didn't make a one-time cut," Lieberman told the annual Herzilya security conference near Tel Aviv, referring to Abbas by his nickname.

"His intention is actually to continue cuts and in a few months to stop paying for fuel, medicines, salaries and many other things.

"In my opinion the strategy is to hurt Hamas and also to drag Hamas into a conflict with Israel."

Hamas seized Gaza from Fatah in 2007 and the two Palestinian factions have had hostile relations since.

The Abbas-led Palestinian Authority had nonetheless continued to pay for electricity and some other services in Gaza.

Abbas recently announced the PA would no longer pay Israel to supply electricity to Gaza, prompting Israel to stop deliveries this week.

The move threatened to leave the two million Gazans with as little as two hours of power a day, prompting warnings of risks of Hamas retaliation.

Israel and Hamas have fought three wars in Gaza since 2008, most recently in 2014.

Lieberman also on Thursday accused its Lebanese arch-foe Hezbollah of expanding observation posts along the border under the cover of an environmental NGO, in what it called a "dangerous provocation".

The Israeli military published pictures of a building near the frontier supposedly controlled by an organisation called Green Without Borders.

"Hezbollah is thus conducting observation missions by claiming they are activities of this environmental organisation," General Hertzi Halevi, who heads the military intelligence services, told a security conference at Herzliya near Tel Aviv.
