The month of June has been the deadliest for foreign troops in Afghanistan since the 2001 fall of the Taleban, official figures show.
Correspondents say it was also the second month in a row in which casualties exceeded those in Iraq.
Military statements throughout June show that at least 45 foreign troops died as a result of war or accidents.
They were serving either with the Nato-led International Security Assistance Force (Isaf) or the US-led coalition.
'Resurgent militia'
More than 40% of the 122 foreign soldiers who have died in Afghanistan during 2008 were killed in June, according to official figures collated by the independent website icasualties.org.
Most were killed by roadside bombs hitting their convoys or patrols. Isaf spokesman Gen Carlos Branco said that the high casualty figures should be seen in the context of a higher number of international troops fighting the Taleban.
