A bag believed to contain RDX - a highly explosive material - was recovered from the Indira Gandhi International Airport in Delhi early this morning. The bag, a black-coloured trolley suitcase, was found near a pillar in the Arrivals area of Terminal 3 by a Central Industrial Security Force (CISF) soldier at 12.56 am. Initial tests - conducted by EVD (explosive vapour detector) and a sniffer dog - have suggested it contains RDX. Authorities have said that a more definitive test can only be conducted after a 24-hour period; for now, the bag has been moved to a "cooling pit".
