Nearly a decade after the 26/11 terror attack, when 10 Pakistani terrorists invaded Mumbai from the sea, it turns out the city's coastline is still not entirely secure against infiltration. During this year's anti-terrorism drill, Operation Sagar Kavach, held on April 4 and 5, one mock terrorist managed to evade the multiple security agencies manning the city's coastline and infiltrate the city.
