cluster bombs

Kirby and other White House officials have defended the administration's recent decision to send Ukraine the controversial bombs.

Democratic U.S. Senator Tim Kaine and Representative Barbara Lee raised concerns on Sunday over the decision by Biden's administration to send cluster bombs to Ukraine to combat the Russian invasion.

From 1964 to 1973, U.S. warplanes dropped more than 270 million cluster munitions on the communist country, one-third of which did not explode.

"Since Russia and Syria have renewed their joint air operations, we have seen a relentless use of cluster munitions."
