Home-grown militants and ex-major behind Bangladesh attacks, police say

DHAKA (Reuters) - Early in June, a man walked into the Dhaka premises of the Ramakrishna Mission, a Hindu centre for spirituality and learning in the Bangladesh capital, and delivered a handwritten note warning of an attack by Islamic State.

Days later, armed policemen were sitting inside the mission's compound among orange-robed monks, the gates outside were closed and fewer people than normal showed up at a medical clinic it runs for the neighbourhood.
