ISAF does not name the nationality of casualties, as a matter of policy.
According to the Daily Mail, the incident happened in Helmand province:
[The NATO troops] were in a vehicle searching for IEDs on a tarmac surface when the device exploded.
The Associated Press reports five Afghans were killed in two separate roadside bomb attacks on Tuesday.
The Taliban launched what it calls its spring offensive on Sunday, according to Reuters, specifically targeting foreign military bases and diplomatic areas.
