Roman Catholic Cardinals are making the final arrangements for Pope John Paul's funeral as hundreds of thousands of mourners continue to descend on security-conscious Rome to pay their last respects.

The Vatican estimates one million people have filed past the pope's body in Saint Peter's Basilica, and it anticipates another 600-thousand today (Wednesday). Many have waited in line for 12 hours or more.

Rome is tightening security because John Paul's funeral is drawing leaders from all over the world, including President Bush and his two immediate predecessors, Bill Clinton and George H.W. Bush.

The cardinals have yet to decide on a date to begin a conclave -- their closed door deliberations at which they will elect a new pope.

According to Church law, the conclave must begin by the 20th day following the pope's death.
