US Senator Bernie Sanders has said he will file legislation seeking to block the sale of offensive US weapons to Israel, citing the toll on civilians of Israel’s campaign against Hamas, Reuters reports.

Sanders, an independent who caucuses with Democrats, said he intended to file Joint Resolutions of Disapproval next week.

“Providing more offensive weapons to continue this disastrous war would violate US and international law,” Sanders said in a statement.

In his announcement, Sanders noted that the Biden administration last month approved arms sales to Israel totalling more than $20 billion that included systems tied to tens of thousands of civilian deaths in Gaza. He said exporting such weapons would violate human rights provisions in the Foreign Assistance Act of 1961 and the Arms Export Control Act.
