Iran on Sunday said it was not convinced Israel would abide by a ceasefire that ended their 12-day war this week.

The most serious escalation to date between the arch-foes erupted on June 13, when Israel launched a bombing campaign in Iran that killed top military commanders and scientists linked to its disputed nuclear programme.

Israel said its aim was to keep the Islamic Republic from developing a nuclear weapon — an ambition Tehran has consistently denied, insisting it has the right to develop nuclear power for civilian purposes like energy.

The fighting derailed nuclear talks between Iran and the United States, a staunch ally of Israel.

In a letter to UN Secretary-General Antonio Guterres published on Sunday, Iran demanded that the United Nations recognise Israel and the United States as being to blame for this month’s war.
