The US Justice Department is investigating a handful of apparently anti-Muslim incidents, including the stabbing of a Muslim cab driver in New York City.
FBI agents and civil rights division investigators also are looking into vandalism and other incidents at mosques or mosque construction sites.
The news comes as attorney general Eric Holder met with Muslim and other religious leaders to discuss the attacks and the uproar over a planned mosque near the site of Ground Zero in New York.
Human limbs found in shark
Bahamian police said they were trying to identify human remains found in the stomach of a tiger shark caught off the Exuma islands.
Forensic investigators were conducting DNA tests on the two legs, two arms and severed torso found inside the 12-foot shark.
The remains appeared to be a couple of days old, but it was not clear whether the person was dead or alive when eaten by the shark.
Police did not rule out the possibility that the remains are those of an impoverished migrant whose boat might have capsized during a risky sea journey to Florida.
Beetlejuice star dies at 58
Glenn Shadix, best remembered for his portrayal of a portly, pretentious designer in Beetlejuice, has died aged 58.
A cause of death was not immediately known, but his sister, Susan Gagne, said that he had been using a wheelchair for mobility and appeared to have fallen in his kitchen and struck his head.
In his most memorable role, Shadix starred as Otho in Beetlejuice, an uppity interior designer who tries his hand at the occult to summon ghosts from the afterlife.
Asteroids will zip past Earth
Nasa said two small asteroids discovered just days ago will zip harmlessly past Earth today, a double flyby that should be visible through a telescope.
The Minor Planet Centre in Massachusetts, which tracks asteroids and comets, determined there was no chance of an Earth collision.
The first asteroid is 32 to 65ft long, while the second is 20 to 46ft long.
