Washington: US warned India off banning the visa of 24 Indian employees in the Iranian ship Grace One. The revolutionary guard, which is declared as terrorist organization by the US, was safeguarding the ship and actions would be taken over US anti-terrorist law. The US decision came out in the back drop of US-Iran row and Briton seized Grace One, the ship owned by Iran and the US forced Briton not to have spared the ship. The authorities rejected the US demand and prepared to release Indians in the ship. The US came out against the bid and warned off revoking the US visa of Indians in the ship. Those who seek the assistance of Revolutionary Guard would come under the ambit of the US anti-terror law.
