The International Court of Justice (ICJ), also known as the World Court, said on Monday that Judge Yuji Iwasawa had been elected as its new president to complete former president Nawaf Salam's term that ends on February 5, 2027.
Salam resigned in January to become Lebanon's prime minister.
Iwasawa, who is Japanese, has been a member of the World Court since 2018 and before that was a professor of international law at the University of Tokyo and chairperson of the United Nations Human Rights Committee.
The ICJ, the UN's highest court and based in The Hague, was established in 1945 to resolve disputes between states.
It recently gained global attention in the ongoing case surrounding genocide accusations against Israel - which it has denied - in the Gaza war.
In July, the ICJ ruled that Israel's occupation since the 1967 Middle East war of Palestinian territories and its settlements in the West Bank and East Jerusalem were illegal and that it must withdraw as soon as possible.
U.S. President Donald Trump fired General Timothy Haugh as director of the National Security Agency on Thursday, according to two officials familiar with the decision, and congressional Democrats denounced the removal of the nonpartisan official from a top security post.
Israel stepped up airstrikes on Syria, declaring the attacks a warning to the new rulers in Damascus as it accused their ally Turkey of trying to turn the country into a Turkish protectorate.
The Trump administration moved forward with the sale of more than 20,000 US-made assault rifles to Israel last month, according to a document seen by Reuters, pushing ahead with a sale that the administration of former president Joe Biden had delayed.
