President Joe Biden called for `significant de-escalation' from Israeli Prime Minister Benjamin Netanyahu on Wednesday after 10 days of Israel's aerial campaign on Gaza Strip. It was Biden's toughest public pressure so far on the US ally, with the president asking Netanyahu in a telephone call to move toward `the path to a cease-fire,' according to a White House statement on their conversation. Pressure has been mounting Biden, too, to do more as the death toll in Israel's aerial offensive on Gaza has topped 200. *This story was edited by Ahram Online.
