JERUSALEM, May 1 (Reuters) - Spain's Telefonica (TEF.MC), Europe's third-largest telecoms company, aims to increase investments in Israel's high-tech sector this year, including in e-health and other consumer-facing business, a senior official said.

Luisa Rubio, who heads Telefonica's innovation arm WayraX, has already made one investment in Israel - Upword, which uses artificial intelligence (AI) to create faster, more efficient summaries from notes.

She said WayraX, which invests small amounts in early-stage funding, is considering investing in two more Israeli startups, with a decision expected in the coming weeks.

"We have already executed the first one and hopefully, at the end of the year we will have another four or five companies coming from Israel," Rubio said in an interview with Reuters after visiting the country last week. "Israel will be one of our most relevant markets in terms of executing new investments."
