Washington:US President Joe Biden's administration has approved a $735 million sale of precision-guided weapons to Israel, according to media reports.
The sale includes the joint direct attack munitions (JDAM) and GBU-39 small diameter bombs, according to The Washington Post.
In a separate report, The Hill news website said that the window for Congress to block the sale is all but closed.

"The notification earlier this month set off a 15-day clock for Congress to act. There are four days left in that window, and it takes 10 days once a resolution of disapproval has been introduced before someone can force a vote to bring it to the floor."
Some Democrats raised concerns about the sales as shelling and airstrikes continued in Gaza, causing more than 200 civilian casualties on both sides.
"While I have supported security assistance to Israel, including by funding the Iron Dome defence system, I have serious concerns about the timing of this weapons sale," House Democrat Joaquin Castro said in a statement.
