India advised its citizens on Friday against travelling to Iran and Israel until further notice in view of the "prevailing situation in the region."
The advisory from the foreign ministry came amid Iran's threats to retaliate against a suspected Israeli airstrike on its embassy in Syria this month.
Countries including the US and Russia have issued similar travel advisories for their staff and citizens in the region.
India's foreign ministry said its citizens in the two countries should observe "utmost precautions about their safety and restrict their movements to the minimum."
It is feared that retaliation by Iran can widen the six-month old conflict between Hamas and Israel in Gaza.
