Israel is yet to respond to Iran's retaliatory air-strikes over the weekend.

Prime Minister Benjamin Netanyahu has options, but they all come at a cost.

World leaders are continuing to call for a de-escalation of tensions in the region.

The risk of an escalation happening is genuine; in Tehran, Israel's enemies were warning again that the smallest Israeli retaliation would be met with a show of force.
