Two Massachusetts beaches were temporarily closed Tuesday after shark sightings, authorities said.
Newcomb Hollow Beach at the Wellfleet-Truro line was closed in the afternoon after Massachusetts State Police said in a tweet that a white shark was spotted by a helicopter "near the swimmers."
Police in Edgartown, on Martha's Vineyard, then tweeted that South Beach had been closed to swimming due to a shark sighting.
It was unclear when either beach would reopen to swimmers.
