The Delhi Police have ramped up security checks across the national capital following a car explosion near Red Fort on Monday and in the wake of the recovery of around 360 kg of suspected ammonium nitrate and a cache of arms and ammunition in Haryana's Faridabad, an officer said on Monday.

A high-intensity blast ripped through a car parked near the Red Fort Monday evening, leaving multiple vehicles in flames and window panes in smithereens.
