India today again strongly advised its nationals to avoid travelling to Yemen under any circumstances by any means for any purpose till further notice in view of fragile security situation. <br/><br/>The latest advisory came in the light of the recent terrorist attacks in Aden, which resulted in killing of an Indian nun and abduction of one priest. External Affairs Ministry said, it had issued several travel advisories last year advising Indian nationals to refrain from undertaking travel to Yemen in view of the precarious security situation in the country.
