Palestinian President Mahmoud Abbas has canceled his participation in a meeting scheduled for Wednesday with  and other Mideast leaders, a senior Palestinian official said.  

Abbas was scheduled to join Jordan’s King Abdullah II and Egyptian President Abdel Fattah el-Sissi at Wednesday’s summit in Amman, Jordan, where they are to discuss the latest Israel-Hamas war with Biden. 

The senior officials said Abbas was withdrawing his presence to protest an alleged Israeli airstrike on a hospital in Gaza that Hamas health officials say killed over 500 people on Tuesday.  

Israel said it is investigating the source of the explosion.

Biden is scheduled to visit Israel Wednesday in a show of support as Israeli forces continue to bombard the Hamas-controlled Gaza Strip. Biden will visit Jordan after the meeting.
