TEHRAN, Young Journalists Club (YJC) - Abbas arrived at a hospital near Ramallah in the occupied West Bank for the operation and was due to be released "in a few hours", the official news agency Wafa said.
The health of the 83-year-old longtime smoker is a topic of regular speculation, with no clear successor identified.
In February, he underwent what was then described as routine medical tests in the United States.
In recent months he has cut off all ties with President Donald Trump's administration after the announcement the US would recognize Jerusalem as Israel's capital and move its embassy there.
