(fxcue news) - Indian shares ended modestly lower on Tuesday, as Middle East tensions intensified and U.S. President Donald Trump's tariff order on movies along with plans to cut reliance on foreign-made medicines reignited concerns about the potential fallout of a global trade war. Investors also reacted to a Bloomberg report that said India has proposed zero tariffs on steel, auto components and pharmaceuticals on a reciprocal basis up to a certain quantity of imports in its trade negotiations with the U.S. Meanwhile, with tensions between India and Pakistan reaching a new high, the Ministry of Home Affairs (MHA) has issued directives to several states, urging them to conduct large-scale civil defence mock drills on May 7. These drills are aimed at assessing the country's preparedness in case of a hostile attack and at the same time raising awareness among the public.
