The EU's top diplomat said that member states are running low on weapons at home because they have given so many to Ukraine.

Josep Borrell, the EU's high representative for foreign affairs and security policy, said on Monday that the military stocks of most member states have been exhausted.

He said during a debate with European lawmakers that countries should buy work together to buy replacements for themselves, as that would be cheaper than each country doing it alone. It's the best way to refill. It will be a lot less expensive.

A $500 million fund was proposed by the EU for member states to buy weapons.

Borrell said that the EU should have started training Ukrainian troops a year ago.

We regret that we did not. We regret that we didn't fulfill this request in August.

He said that the EU would have been better off if it had done it.

In February, Russia invadedUkraine.

The EU has given over $2 billion in weaponry to Ukraine.

Some of the weapons they are giving to Ukraine are from countries that already have weapons. It means that the equipment can arrive in Ukraine quicker than in other countries.
