Google on Wednesday updated how it handles political ads as online platforms remain under pressure to avoid being used to spread misleading information intended to influence voters.

The internet company said its rules already ban any advertiser, including those with political messages, from lying in ads. But it is making its policy more clear and adding examples of how that prohibits content such as doctored or manipulated images or video.

"It's against our policies for any advertiser to make a false claim -- whether it's a claim about the price of a chair or a claim that you can vote by text message, that election day is postponed, or that a candidate has died," Google ads product management vice president Scott Spencer said in an online post.

Pope Francis will visit one of Thailand's famed gilded temples Thursday to meet the supreme Buddhist patriarch, on the first full day of his Asian tour aimed at promoting religious harmony.

The 82-year-old pontiff is on his first visit to Buddhist majority Thailand, where he will spend four days before setting off to Japan.

His packed schedule a day after touching down in Bangkok includes a meeting with the king and the prime minister before leading an evening mass expected to draw tens of thousands of people from across Thailand, where just over 0.5 percent of the population is Catholic.
