Former Pakistani military ruler Pervez Musharraf's bodyguards spirited him out of an Islamabad courtroom Thursday to avoid his arrest on treason charges after a judge revoked bail.

Police in the courtroom made no attempt to detain Musharraf, 69, who was whisked away by his security detail to his residence in a suburb of the capital.

The BBC's Orla Guerin described the scene at the courthouse as "a moment of high drama and farce."

A bipartisan compromise that would have expanded federal background checks for firearms purchases has been rejected by the Senate.

The defeat of the measure by a 54-46 vote — six votes shy of the number needed to clear the Senate — marks a major setback for gun-control advocates, many of whom had hoped that Congress would act to curb gun violence in the wake of December's Newtown elementary school massacre, where 20 students and six adults were killed.

Scientists have unraveled the genome of the coelacanth, a rare and primitive fish once thought to be extinct, shedding light on how closely it's related to the first creatures to emerge from the sea.

The coelacanth, a fish that can reach up to 5 feet long and lives in deep ocean caves, had only been seen in fossils and was thought to have gone extinct some 70 million years ago. That was until 1938, when fishermen from the Comoros islands off the coast of Africa captured one in a net. A second coelacanth species was discovered off the Indonesian island of Sulewesi in 1997.
