The US secretary of state has determined that "an emergency exists that requires the immediate sale to the government of Israel" of the weaponry.

The United States on Friday announced the approval of a $147.5 million sale of 155mm high-explosive artillery munitions and related equipment to Israel under an emergency provision that waives the usual congressional review.

The same provision was used earlier this month to approve the sale of nearly 14,000 rounds of 120mm tank ammunition to Israel, which is battling Hamas in Gaza in a highly destructive conflict that began with a shock attack by the Palestinian militants in October.

Israel requested that 155mm fuses, primers and charges be added to previous foreign military sale cases, increasing their estimated total cost from $96.51 million to $147.5 million and requiring a new notification, the US Defense Security Cooperation Agency said in a statement.

The secretary of state has determined that "an emergency exists that requires the immediate sale to the government of Israel" of the weaponry, thereby waiving the normal requirement for review by Congress, according to the statement, which said the munitions will come from US Army stocks.

"Israel will use the enhanced capability as a deterrent to regional threats and to strengthen its homeland defense," the statement said, adding: "It is incumbent on all countries to employ munitions consistent with international humanitarian law."

The civilian deaths and the destruction in Gaza from the Israeli campaign has caused a growing international outcry, and the United States' international image has taken a beating over its continued backing for Israel.
