Palestinian Authority President Mahmoud Abbas has been taken to hospital in the West Bank for heart tests.
Mr Abbas, 81, had been feeling "fatigued," according to Palestinian sources.
The president's doctors performed a cardiac catheterisation, a procedure in which a thin plastic tube is inserted into the heart via an artery or vein to assess any blockages, one of the sources told Haaretz.
A Palestinian doctor told Reuters on Thursday that Mr Abbas's heart test results were normal. "He will leave hospital in the next two hours," the doctor said.
