hasn't made public any details about the case, the Indian government said Thursday it's exploring legal options after it received initial information about the sentencing. The Indian government expressed “shock" over the sentencing and said in a statement, “We are deeply shocked by the verdict of the death penalty and are awaiting the detailed judgment." The former Indian Navy personnel are Captain Saurabh Vashisht, Commander Purenendu Tiwari, Captain Birendra Kumar Verma, Commander Sugunakar Pakala, Commander Sanjeev Gupta, Commander Amit Nagpal and Sailor Ragesh. All of these former Navy officers had "unblemished stints" of up to 20 years in the Indian Navy.

"They had held important positions including that of instructors in the force," sources told the news agency PTI. "The former personnel had impeccable service records and had taken voluntary retirements in search of greener pastures," it said. According to an NDTV report, Commander Purnendu Tiwari was awarded the Pravasi Bharatiya Samman in 2019.

It is the highest honour conferred on overseas Indians. According to reports, the Al Dahra security company had some arrangements with the Qatari authorities for facilitating training to naval personnel. "The men were training Qatari Navy personnel in the country," Bloomberg reported.

The company provided training and other services for Qatar's armed forces. In May, private firm Al Dahra Global Technologies closed its operations in Doha and all those working there (primarily Indians) have since returned home. Al Dahra Global Technologies is a defence services provider company, owned by an Omani national, Khamis al-Ajmi, a retired squadron leader of the Royal Oman Air Force, the Indian Express said.
