The Biden administration is holding up shipments of two types of Boeing-made precision bombs to send a political message to Israel, according to a US official and six other people with knowledge of the deliberations.

According to Politico, the US has yet to sign off on a pending sale of Boeing’s Joint Direct Attack Munitions — both the munitions and kits that convert them to smart weapons — and Small Diameter Bombs, according to six industry and congressional sources with knowledge of the discussions.
