The US has announced its fifth round of sanctions since October 7 on what the Department of the Treasury say are Hamas-linked individuals and businesses, Al Jazeera reports.

Matthew Miller, spokesperson for the Treasury said the new measure targets “networks of Hamas-affiliated financial exchanges in Gaza, their owners, and associates”.

“In conjunction with this action, Australia and the UK are also placing sanctions on key Hamas officials and facilitators,” he said.

Britain’s foreign office said its sanctions targeted Zuheir Shamlakh, a man known as Hamas’ “main money changer”, and a key figure involved in the group’s shift towards cryptocurrencies who helped transfer money from Iran to Hamas ahead of the group’s October 7 attacks.

“These sanctions send a clear message to Hamas — the UK and our partners are committed to ensuring there is no hiding place for those financing terrorist activities,” British Foreign Secretary David Cameron said.
