Israel's prime minister will take "strong action" against boycotts, after Ben & Jerry's decided to stop selling ice cream in Israeli settlements in the occupied Palestinian territories.
Naftali Bennett warned the US firm's parent company, Unilever, that there would be legal and other consequences.
Ben & Jerry's said on Monday that the sale of its products in the West Bank and East Jerusalem was "inconsistent with our values".
Palestinian activists praised the move.
