What is the difference between tikka and bhuna?

Tikka is a dish prepared by grilling the pieces of chicken or paneer or meat on charcoal (without keeping the pieces directly on coal, but in heat of coal) or traditional tandoor while bhuna means to cook or grill something by putting it directly on coal.

To grill tikka, the pieces of (lets say) marinated paneer are hanged above burning coal with the help of rod. The distance between burning coal and paneer pieces is approx 10-20cms depending upon the heat required.

Bhuna means to grill something by directly placing it on burning coal. There is direct contact between item to be grilled and coal, but in Tikka there is no direct contact of coal and item to be grilled.
