Multiple web search results report that US forces intercepted a tanker in the Indian Ocean and that the tanker's position was tracked near Sri Lanka. Specifically, one web search result mentions the tanker altering course and transmitting its position around 700 km south-east of Sri Lanka, which is consistent with the claim. Another web search result also details the US boarding of a sanctioned tanker in the Indian Ocean.

Two separate web search results corroborate the details regarding the tanker Tifani, its carrying capacity, and its recent movements. One source explicitly states: 'According to MarineTraffic, the tanker Tifani, with a carrying capacity of nearly 300,000 tonnes, is currently loaded and changed direction in the early hours of yesterday.' Another web search result mentions the tanker Tifani in the context of US forces detaining it.

Multiple web search results confirm that the tanker Tifani is linked to sanctions and alleged ties to Iran. Specifically, one source states the vessel is 'under sanctions for smuggling Iranian crude,' and another mentions it is 'linked to ENSA Ship Management Private Limited, an Indian shipping company sanctioned for alleged ties to Iran.' This corroboration comes from multiple independent web search snippets.

Two web search results provide specific tracking data corroborating the timeline mentioned in the claim. One web search result states: 'Tracking data shows that the tanker departed the Gulf region on April 10 and made a brief stop near Sri Lanka's southern port of Galle on April 18 before being intercepted by US forces.' This is supported by the general context of other web results detailing the interception and movement near Sri Lanka.
