Indian border guards have arrested 150 Bangladeshis who sailed into India in what security officials Saturday called the biggest interception of illegal migrants in decades. The arrests were made Friday when the immigrants, who included 36 women and 40 children, sailed into India in two speed boats through the Ichamati and Raimongal rivers that flow through the South Asian countries. "After 1971, this is first time so many Bangladeshi nationals were arrested while crossing the border," India's Border Security Force inspector general C.V Muralidharan said.
