Kolkata: The Congress on Saturday held a protest rally here to condemn the twin terror attacks in Bangladesh. Led by West Bengal unit president Adhir Ranjan Chowdhury, Congress activists and supporters called on the people at large to combat terrorism. "We cannot sit quietly and watch our neighbouring country, Bangladesh, being blood smeared. "People from every sphere will have to participate in combating terrorism which is being perpetrated in the name of religion," said Chowdhury. While in the July 1 attack in a cafe in Dhaka 20 hostages, mostly foreigners, were killed, on Thursday, Bangladesh witnessed a fresh attack on the Eid day at Kishoreganj's Sholakia, in which four people including two policemen lost their lives.
