French President Emmanuel Macron has told caretaker Prime Minister Najib Mikati that France would do "everything in its power" to stop violence spiralling between Lebanon and Israel, his office said.

Hamas political leader Ismail Haniyeh will meet Turkey's President Recep Tayyip Erdogan on Saturday with Middle East tensions at a high after Israel's reported attack on Iran and Gaza bracing for a new Israeli offensive.

French authorities on Friday detained a man after receiving an alert from the Iranian consulate in Paris that someone had entered carrying an explosive, the capital's police authority said.

"The man has exited the consulate and is being controlled" by police, it said, after a security source told AFP that the mission called in law enforcement following a witness seeing a man enter carrying a grenade or an explosive belt.
