BBC News, on the Afghan-Iranian border
In a cavernous UN reception tent on the Afghan-Iranian border, eight men and a young boy sat and drank tea at a white plastic table.
Two of the men had bandages around their heads and another wore a neck brace.
The group of Afghans had been packed into a speeding vehicle on the way to the Iranian capital, Tehran, when they had swerved to avoid an oncoming vehicle.
