Ethiopia warns of 'all-out invasion' by Eritrea, vows self-defense

Ethiopia has formally accused Eritrea of launching an 'all-out invasion' in a letter to the UN Security Council, signaling a major escalation in bilateral tensions. The claim is unverified and likely part of a diplomatic offensive, but it raises the risk of renewed large-scale conflict in the Horn of Africa. The international community's response will be critical in determining whether this leads to open war.
