Erdogan is the latest in a string of regional leaders, including Palestinian Authority President Mahmoud Abbas and Jordan's King Hussein to warn of negative implications of the move. The possibility that Trump may make the announcement has also stirred opposition from US officials who fear it could unleash
Such a decision, which US officials have said has not been finalized, would violate decades of US policy not to take a stance on the fate of Jerusalem on the grounds that this was an issue Israelis and Palestinians should negotiate and decide.
If Trump made such a move, it could spark demonstrations or violence by Palestinians or by Muslims around the world, in part because of the sensitivity of the Jerusalem site known to Jews as the Temple Mount and to Muslims as Haram al-Sharif.
Israel's Education Minister Naftali Bennett was quick to respond.
"Unfortunately, Erdogan does not miss an opportunity to attack Israel. Israel must advance its goals, including the recognition of United Jerusalem as the Capital of the State of Israel," Bennett said in a statement. "There will always be those who criticize, but at the end of the day it is better to have a united Jerusalem than Erdogan's sympathy."
According to Channel 10 sources, Israeli Prime Minister Benjamin Netanyahu told the Knesset Foreign Affairs and Defense Committee on Monday that Israeli security forces are prepared for an escalation in violence should Trump announce US recognition of Jerusalem as Israel's capital.
"We are prepared for every possibility. The security forces know best how to act, if and when it is necessary," Netanyahu is reported to have told the committee's members.
