Prime Minister Benjamin Netanyahu is demanding that German Foreign Minister Sigmar Gabriel, who arrived on Monday for a visit to Israel, cancel his planned meeting on Tuesday with representatives of B’Tselem and Breaking the Silence.

Senior officials in the Prime Minister’s Office said that Netanyahu issued an ultimatum to Gabriel, saying that if the latter does not cancel his meetings with the left-wing groups, the prime minister won’t meet with him. The ultimatum was first reported by Israel Channel 2 News.
