NEW DELHI - India seized 200 kg of heroin from drug traffickers aboard a boat on the Arabian Sea, a defence official said on Tuesday. A joint navy and coastguard operation intercepted the vessel in Indian waters on Monday, apparently headed for the western state of Gujarat, Indian navy spokesman DK Sharma said. “Using fishing boats to smuggle heroin is a new strategy by Pakistani smugglers,” said Sharma, adding that the smugglers were using phones and GPS systems to allow trans-shipment to another boat.
