Turkish President Reccep Tayyip Erdogan has said that Islamic countries should form an alliance against what he called “the growing threat of expansionism” from Israel, Reuters reports.

He made the comment after describing what Palestinian and Turkish officials said was the killing of a Turkish-American woman by Israeli troops in the Israeli-occupied West Bank.

“The only step that will stop Israeli arrogance, Israeli banditry, and Israeli state terrorism is the alliance of Islamic countries,” Erdogan said at an Islamic schools’ association event near Istanbul.

He said recent steps that Turkiye has taken to improve ties with Egypt and Syria are aimed at “forming a line of solidarity against the growing threat of expansionism,” which he said also threatened Lebanon and Syria.

Israel did not immediately comment on Erdogan’s remarks on Saturday.
