The blast that killed the Americans took place yesterday somewhere in the south, according to a NATO statement, but no other details were available. The British soldier died in Helmand province. Afghan insurgents are increasingly turning to improvised explosive devices in their fight against Afghan and international forces. Of the 304 US military deaths in Afghanistan last year, 129 were due to IEDs or roadside bombs, according to an AP tally. Also today, NATO said a joint Afghan-international force discovered a huge cache of marijuana and turned it over to police for destruction.
