A mass felling of trees in one of the world's most-polluted megacities was halted by India's top court Monday, amid
protests their removal would strip the city of a precious "green lung".
Some 2,700 trees were being cut down in the financial capital Mumbai to make way for a depot for subway carriages in the city of nearly 20 million people.
More than two dozen activists were arrested during weekend protests were all later released on bail,
police said.
