UPDATE 3-Striking teachers reach deal with Los Angeles school district

A week-old strike by more than 30,000 Los Angeles teachers that has disrupted classes for nearly half a million students neared an end on Tuesday as the teachers' union and the country's second-largest school district reached a contract deal. If the union's members vote to approve the deal, they will return to work on Wednesday, Mayor Eric Garcetti said at a news conference.
