President Recep Tayyip Erdogan said Turkey stood in solidarity with Lebanon amid growing tensions with Israel and called on regional countries on Wednesday to also support Beirut, Reuters reported.

Cross-border strains between Israel and Lebanon's Hezbollah have been escalating in recent weeks, stoking fears of an all-out Israel-Hezbollah war.

In a speech to his AK Party lawmakers in parliament, Erdogan said Israeli Prime Minister Benjamin Netanyahu planned to spread the Gaza war to the region.

"It seems that Israel has now turned its eyes on Lebanon after destroying and burning Gaza. We see Western countries giving Israel support behind the scenes," Erdogan said.

"Netanyahu's plans to spread the war to the region will lead to a big catastrophe," he said, adding that the Western support for Israel was "pitiful".

"Turkey stands with the brotherly people and state of Lebanon. I call on other countries in the region to stand in solidarity with Lebanon," he said.
