New Delhi:
An attack at two Taiwan tourists near Jama Masjid shattered Delhi's Sunday morning calm. Chief Minister Sheila Dikshit was quick to reassure the city that there is "no reason to worry".
But not everyone was convinced, especially those participating in the Commonwealth Games just a fortnight away. Almost instantly after the firing incident, security concerns got more serious.
The command and control centre set up for liaison with participating countries was suddenly flooded with calls.
Inquiries were made by countries like Australia, Canada and the UK, who have raised concerns about security in the past.
It's a nightmare for the security forces, under pressure to ensure an incident free Games.
Almost 1 lakh security personnel, most of them from the Delhi Police, are already on the streets. Coupled with this, 18,000 men from the Central Police Organisations, 3000 Commandos, 200 dog squads and 20 bomb squads will be on duty.
Security agencies have already secured the venues, the Games village where the athletes will be put up, shopping areas and markets popular with foreigners. But Sunday's attack underscores the enormity of the challenge.
With athletes' arrival scheduled to begin in 3-4 days, this incident could lead to a rethink and perhaps further fine security tuning for the Games.
