NEW DELHI (AP) — Tens of thousands of protesting farmers have driven long lines of tractors into India’s capital, breaking through police barricades, defying tear gas and storming the historic Red Fort as the nation celebrated Republic Day. They waved farm union flags from the ramparts of the fort, where prime ministers annually hoist the national flag to mark the country’s independence. Thousands more farmers marched on foot or rode on horseback while shouting slogans against Prime Minister Narendra Modi. For nearly two months, farmers have blocked highways connecting the capital with the country’s north in a rebellion that has rattled the government. They are demanding the withdrawal of new laws which they say will commercialize agriculture and devastate farmers’ earnings.
