Left-wing protesters write slogans on signs before a protest condemning Friday's arson attack in the West Bank, at Rabin square in Tel Aviv August 1, 2015. Some 3,000 demonstrators gathered for the rally organised by the Israeli anti-settler group Peace Now against the attack by suspected Jewish assailants who torched a Palestinian home in the occupied West Bank on Friday, killing an 18-month-old toddler and seriously injuring three other family members, an act that Israel's prime minister described as terrorism.
