Indian Prime Minister Narendra Modi's political troubles deepened with his Bharatiya Janata Party appearing to lose control of the mineral-rich eastern state of Jharkhand in state poll results out Monday.

The results come as the government struggles to contain growing nationwide protests against a new federal religion-based citizenship law that's seen at least 24 people killed in clashes between police and demonstrators.

The poor showing will add pressure on the government as it presides over an economy that's growing at its slowest rate in six years and with unemployment running at the highest in four decades.
