Turkish President Tayyip Erdogan said on Saturday Islamic countries should form an alliance against what he called "the growing threat of expansionism" from Israel.

He made the comment after describing what Palestinian and Turkish officials said was the killing by Israeli troops of a Turkish-American woman taking part in a protest on Friday against settlement expansion 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 Turkey 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.

Erdogan hosted Egyptian President Abdel Fattah al-Sisi in Ankara this week and they discussed the Gaza war and ways to further repair their long-frozen ties during what was the first such presidential visit in 12 years.

Ties between them started thawing in 2020 when Turkey began diplomatic efforts to ease tensions with estranged regional rivals, including the United Arab Emirates and Saudi Arabia.

Erdogan said in July that Turkey would extend an invitation to Syrian President Bashar al-Assad "any time" for possible talks to restore relations between the two neighbours, who severed ties in 2011 after the outbreak of the Syrian civil war.

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

Israel's military said after Friday's incident that it was looking into reports that a female foreign national "was killed as a result of shots fired in the area. The details of the incident and the circumstances in which she was hit are under review.

There was no immediate comment on Friday's incident from Israeli Prime Minister Benjamin Netanyahu's office.
