President Joe Biden's administration has informed the U.S. Congress that it is planning a $320 million transfer of precision bombs for Israel, a source familiar with the plan said on Monday.

The Wall Street Journal first reported that the administration sent formal notification on Oct. 31 to congressional leaders of the planned transfer of Spice Family Gliding Bomb Assemblies, a type of precision guided weapon fired by warplanes.

Citing correspondence it viewed, the Journal said weapons manufacturer Rafael USA would transfer the bombs to its Israeli parent company Rafael Advanced Defense Systems for use by the Israeli defense ministry.

Earlier on Monday, the United Nations said Gaza is becoming a "graveyard for children," amplifying demands for a ceasefire as Palestinian health authorities said the death toll from Israel strikes had exceeded 10,000.
