Saudi Arabia has helped India with a major breakthrough in the probe into the 26/11 attacks by facilitating the arrest of Syed Zabiuddin Ansari alias Abu Jundal, one of the key plotters of the Mumbai raid. Jundal, who directed Ajmal Kasab and other 26/11 attackers from the Lashkar control room, was picked up by the Saudi police, who put him on a New Delhi-bound flight after alerting the authorities here about their prize catch.
