US jihadists fail to build significant networks, act alone

WASHINGTON: Sayfullo Saipov, the radicalized Uzbek who mowed down eight people on a New York bike path, apparently developed his plot in relative isolation, like most other jihadist attackers in the United States.

But in Europe many have had community support, an underground network, or even a hardline Islamist to guide them, as in the twin attacks in Spain in August.
