US President Joe Biden arrived in Berlin on Friday for talks with German leaders on Western support for Ukraine and the volatile situation in the Middle East.

Biden is scheduled to meet with German President Frank-Walter Steinmeier and Chancellor Olaf Scholz, and their talks are expected to focus on strengthening transatlantic ties and supporting military aid to Ukraine.

Germany is currently Ukraine's second largest donor after the US and has provided advanced weapons such as Leopard 2 battle tanks, Patriot missiles and IRIS-T air defense systems.

Biden's visit comes at a time of growing doubt about the future of Western aid to Ukraine, due to the US election - less than three weeks away - and the possibility of a second term for former President Donald Trump.

Trump and his Republican Party have been far less supportive of helping Ukraine fight Russia, with some party members calling for aid to be cut off entirely.

After his talks with German leaders, Biden is also scheduled to hold a meeting with Chancellor Scholz, French President Emmanuel Macron and UK Prime Minister Keir Starmer.

“President Biden looks forward to having a conversation with other leaders about the critical issues of the day, which obviously include Russia's war against Ukraine, the situation there; also the situation in the Middle East, finding a lasting diplomatic solution to the conflict now between Israel and Lebanon, of course, the risk of escalating the situation with Iran," a White House official said before the visit.

Biden's farewell visit to Berlin, after his term in office ends in January, was originally planned for a week ago, but was postponed due to Hurricane Milton, which threatened mass destruction in the state of Florida.

Berlin police were put on high alert during Biden's visit, and around 2,500 police officers were deployed to beef up security and secure Biden's route from Brandenburg Airport to the city center.

Roads around the main government buildings were closed and snipers were placed on top of the buildings. Local authorities have warned residents to expect significant traffic disruptions on Friday./AA
