On August 3, around 30 heavily armed Tamil rebels crossed a lagoon and entered the town of Kattankudi. At around 8.10PM, they entered the Meer Jumma, Husseinia, Majid-Jul-Noor and Fowzie Mosques, where hundreds of devotees were attending Friday Isha prayers. The LTTE cadres were disguised as Muslims to avoid suspicion.As the civilians knelt in prayer, the Tamil rebels attacked them, spraying automatic fire and hurling hand grenades at the worshipers. Most of the victims were shot in the back or side. The rebels fled as
Sri Lankan soldiers, notified of the ongoing massacre, arrived at the scene.
Initial report put the death toll at around 100, but as many of the injured who were rushed to hospital succumbed to their injuries, the final death toll rose to over 147.
