The United States is defending a decision to send controversial cluster bombs to Ukraine.
US President Joe Biden has called it a "difficult decision" but says he had to act, as "the Ukrainians are running out of ammunition".
The explosives - banned in more than 100 countries - can pose a high risk to civilians, as they don't always detonate on impact.
But former British army officer, Major General Rupert Jones, believes the use of cluster bombs is justified:
"They've got a bad reputation of course. The munitions the Americans are going to provide have a much lower, what people call, 'Dud Rate' - the Americans say about 2.5%. The reality is, after the war, the conflict zone is going to be uninhabitable for a very significant period of time".
