Donald Trump and Benjamin Netanyahu sharing a kiss on a West Bank wall mural was believed to be the work of Australian graffiti artist Lushsux.

His face hidden by a headdress, a man who identified himself as Lushsux said against the backdrop of a cement section of the Israeli wall in Bethlehem that he hoped his painting of the U.S. president and Israeli prime minister would draw attention to Palestinians stuck in "an indoor prison," Reuters reported.

The Bethlehem wall has become a showcase of protest art voicing Palestinians' fears that Israel's West Bank fence-and-concrete barrier is a land grab that may deny them a state. Israelis deem the project a bulwark against Palestinian attack.

"The wall is a message in itself," the man, who said he painted the mural overnight, told Reuters. "I don't need to write 'Free Palestine' or something like that, something really direct ... that people will ignore.

"I just paint what I usually paint and maybe people will start looking at the background and looking at the razor wire and looking at people stuck in here, and maybe that'll work better," he said in Australian-accented English.

Murals on the barrier believed to be the work of Lushsux include one showing Trump kissing an Israeli watchtower and another depicting him placing his hand on the barrier and thinking about building a similar wall on the U.S. border with Mexico.
