United States President Joe Biden said on Thursday that the potential ceasefire agreement between Israel and Hamas is unlikely to be reached by March 4 as he had initially predicted, Agence France Presse (AFP) reported. In response to the correspondent’s question whether Israel’s attack on the Gaza aid line, which is said to have killed over a hundred Palestinians, would complicate the warring parties’ negotiations on a temporary armistice, Biden said, “I know it will.” “We’re checking that [incident] right now. There are two competing versions of what happened, I don’t have an answer yet,” the US president stressed.
