The escalating conflict between Israel and Iran is likely to be high on the agenda as world leaders gather in Canada on Monday.

Iran launched a fresh attack on Israel late Sunday, with an explosion seen in the coastal city of Haifa. Israel began further attacks on military targets in Iran, despite international calls for diplomacy and de-escalation, per CNN.

What were the targets of Israel’s attack? Israel appeared to widen its attack, striking missile infrastructure in the west of the country and hitting targets in the east. Tehran shook with multiple large explosions, including one near the foreign ministry building, signalling a serious escalation.
