BETHLEHEM, West Bank — President Donald Trump condemned the “evil losers” responsible for the deadly attack on concert-goers in England today and called on leaders in the Middle East in particular to help root out violence.

More than 20 people were killed by an apparent suicide bomber.

“The terrorists and extremists and those who give them aid and comfort must be driven out from our society forever,” Trump said during remarks in Bethlehem with Palestinian Authority President Mahmoud Abbas. “This wicked ideology must be obliterated.”

Trump spoke on his fourth and final day in the Middle East. After meetings with Arab leaders in Saudi Arabia, the president has been pushing the prospect of peace between the Israelis and Palestinians.

Standing alongside Abbas, Trump said an agreement with Israel could “begin a process of peace all throughout the Middle East.”

Abbas said he was keen to “keep the door open to dialogue with our Israeli neighbors.” He reiterated the Palestinians demands, including establishing a capital in East Jerusalem, territory Israel claims as well.
