Tunisia beach killer had accomplices, official says, with British death toll reported to hit 30

The student who massacred holidaymakers on a Tunisian beach and at a swank resort hotel acted alone during the attack but had accomplices who supported him beforehand, an Interior Ministry official said.
Police were searching nationwide for more suspects after the slaughter of at least 38 people in Sousse on Friday, in Tunisia’s deadliest ever such attack. Media reports said 30 of the victims were British.
The attacker’s father and three roommates were detained and being questioned in the capital, Tunis, Interior Ministry spokesman Mohamed Ali Aroui said Sunday.
