Senator's 10-hour speech blocks Texas abortion bill

Texas Democrats have managed to block a bill that would shut most of the abortion clinics in the state.

Democratic state Senator Wendy Davis spoke for more than 10 hours, in a stalling speech known as a filibuster, at the state capitol in Austin.

Republicans then scrambled to pass the bill, but the vote was ruled too late for a midnight deadline.

The bill would ban abortions after 20 weeks of pregnancy.
