U.K. Prime Minister Theresa May will press the global leaders at the G20 to take a harsher line in tackling terror financing, the BBC reported on Friday.

The global financial system can not offer "safe spaces" for financing terrorism, May is expected to tell leaders at the summit in Hamburg.

"We must [...] combat the threat from every angle," the prime minister said ahead of the summit. "This includes taking measures against permissive environments for terrorist financing, and monitoring the dispersal of foreign fighters from battle."

A string of terror attacks in the U.K. this year, including an attack targeting concert-goers in Manchester and attacks in London and Finsbury Park, has sparked a political debate over security and tackling violent extremism.

The country needs to be "far more robust" in identifying and stamping out extremist views, the prime minister said in the aftermath of the London Bridge attack last month.

May faced criticism from a number of opposition leaders, including Labour leader Jeremy Corbyn, for dodging "difficult conversations" with Saudi Arabia over its role in funding terrorism and urged her to use the summit to put pressure on the country, the Guardian reported.

The prime minister's stated objectives for the summit also include migration, modern slavery and the economy, according to the Guardian.

May is slated to meet U.S. President Donald Trump in Hamburg on Saturday to speak about the threat of North Korea and climate change. She has two other bilateral meetings on her agenda, with Chinese President Xi Jinping on Friday and Indian Prime Minister Narendra Modi on Saturday.
