News of the alleged death of Seks's son appeared earlier today when Seks cancelled an official trip to Israel.
The news could not be confirmed either at the Parliament or the Foreign Affairs Ministry, which cares for Croatian citizens abroad.
Domagoj's mother Marija is expected to accompany Seks, according to unofficial information.
Domagoj visited India on a number of times, staying for several months.
Deputy speaker Luka Bebic will act as parliament speaker during Seks's absence.
