On Friday, the Delhi Police issued a statement that said a blast at the Israel Embassy was a 'mischievous attempt to create sensation'. However within 24 hours, the Special Cell was busy writing to the Foreigner Regional Registration Offices (FRRO) asking for details of all Iranians, including those who were visiting the national capital.
High alert was sounded in the country with heightened security at embassy areas, airports and markets.
A letter found at the site mentioned the explosion was just a "trailer" and went ahead with mentions about Iran's slain General Qasem Soleimani and top nuclear scientist Mohsen Fakhrizadeh as "martyrs" -- suggesting the blast that looked like a minor explosion might be a bigger security threat India could be dealing with.
Within hours, Ambassador of Israel to India Ron Malka issued a statement expressing concern.
"The incident is under investigation by the authorities in India who are in contact with the relevant Israeli authorities. Authorities from both sides are cooperating in the investigation. We will continue to update as there are developments," Malka said.
