You do not need to be a foreign looking and fair skinned to become a foreigner.Anyone with a citizenship can become a foreign national.For example,pakistani youths involved in tubular attacks,and other subversive activities in Europe.
That's completely irrelevant to the point being made.
The attackers were explicitly described as "foreign looking," not as "foreign nationals." I'm simply pointing out that the attackers we have pictures of look very Indian.
