Prime Minister Narendra Modi's longstanding bonhomie with President Donald Trump may be tested as the Indian leader kicks off a visit to Washington, eager to avoid tariffs that have been slapped on others and threats of further taxes and imports.

Tariffs, deportations and a brewing storm over Iran could unsettle ties held together by shared concerns over China.

In a major counter-terrorism move, President Trump announced the approval of the extradition of Tahawwur Rana, a key suspect in the 2008 Mumbai attacks. This marks a significant step in the US-India fight against terrorism and highlights the growing security collaboration between the two countries.
