LONDON: Palestinian President Mahmoud Abbas has praised US President Donald Trump for his efforts to achieve a ceasefire between Iran and Israel and prevent a potential full-scale war in the Middle East. In a letter, Abbas also called on the US president to stop the Israel-Hamas war in the Gaza Strip, which began in October 2023 and which has resulted in the killing of more than 54,000 Palestinians, most of them women and children, and the displacement of millions.
