India booked a semi-final berth in the women's Twenty20 World Cup after humbling Sri Lanka by five wickets in a rain-marred pool B match, here today.

Punam Raut hit a patient 30 off 40 balls, while Mithali Raj cracked an unbeaten 22-ball 32 to help India romp home after restricting the Lankans to a paltry 94 for six in a rain-reduced 18 overs per side match at County Ground here.
