Iran and Israel trade fire in first clash since the truce.

On Monday, Iran and Israel launched attacks on each other’s territory for the first time since a fragile ceasefire paused five weeks of fighting, raising concerns that the situation could spiral into a new full-scale conflict.

Overnight, Iran launched a barrage of missiles at Israel, prompting Israel to strike military sites in the Islamic Republic. Israeli Prime Minister Benjamin Netanyahu seemed to ignore calls from his ally, President Donald Trump, to show restraint.

Tehran’s strikes followed attacks by Israel against targets of the Iran-backed Lebanese Shia group Hezbollah in the southern suburbs of Beirut. Iran had repeatedly warned it would strike Israel if the Lebanese capital was targeted.

Oil prices jumped on renewed fears of war, dashing hopes for a quick resolution to the standoff that’s been restricting shipping through the vital Strait of Hormuz and raising concerns about global energy and goods shortages.

The strikes also came at a critical moment with diplomatic efforts to end the conflict involving mediator Pakistan on a knife-edge.

Iranian foreign ministry spokesman Esmaeil Baqaei warned at a press conference in Tehran attended by AFP that is was “perfectly natural that the diplomatic process initiated to put an end to this imposed war would be affected.”

But he added: “Diplomatic consultations are naturally continuing in all circumstances.”

As he was speaking at the foreign ministry, a huge explosion shook the building, followed by repeated explosions believed to be from air defence systems, the AFP reporter said.

No casualties have been reported so far in either Israel or Iran.

The Israeli military said it struck and dismantled Iranian defence systems deployed across several areas in the country.

AFP journalists in Jerusalem and the West Bank city of Ramallah heard a series of explosions and the Israeli army said it worked to intercept a new wave of Iranian missiles.

Iran’s Revolutionary Guards said they had struck Israel’s Nevatim and Tel Nof air bases and had also targeted a petrochemical facility in Israel in retaliation for an attack on a similar site in southwestern Iran.

The Guards warned that Israel “has initiated a dangerous game, the scope of which will encompass all energy-related targets in the region”.

Foreign ministry spokesman Baqaei blamed the US for the flare-up, saying “no-one believes” Israel would carry out any action “without prior coordination and cooperation with the United States”.
