Lahore, Pakistan - Pakistani police have arrested six people allegedly linked to attacks on two mosques in May that killed at least 80 people in Lahore.
Authorities on Monday said they seized almost 18,000kg of explosives, 21 grenades, six-47s and a lot of bomb-making material from the the group.
Aslam Tareen, Lahore's police chief, said the suspects were running "a sort of bomb-making factory".
He said four of the suspects provided logistical support to the attackers by purchasing motorcycles, cell phones and SIM cards.
On May 28, 2010, attackers and suicide bombers stormed two mosques belonging to the minority Ahmadi sect in Lahore shortly after Friday prayers.
It was the deadliest attack on Pakistan's second biggest city.
Tareen said the arrested suspects belong to the banned armed group Harakat al-Jihad al-Islami, as do those who carried out the attacks.
