The call at the annual summit of Group of Eight industrial countries came just days before a crucial meeting about Iran's nuclear programme in Baghdad.
"We desire a peaceful and negotiated solution to concerns over Iran's nuclear program, and therefore remain committed to a dual-track approach," the G8 leaders said as their summit came to a close at the US presidential retreat.
The dual-track refers to the combination of heavy sanctions and serious talks.
Iran says its nuclear facilities are for peaceful use only. Israel has said it has not ruled out an attack on Iran's nuclear facilities if Tehran does not comply in the near future.
The G8 expressed "grave concern" about Iran's nuclear programme, which is suspected of being used to develop nuclear weapons, and called on Iran to "seize the opportunity" of the next round of meetings.//DPA
