Egypt's military has carried out dawn bombings of Islamic State targets in Libya, according to reports by state television.
Seven days of mourning were declared in Egypt after Islamic State militants released a video claiming to show the murder of 21 Egyptian Christians kidnapped in Libya.
The video has been condemned by governments around the world, while the Egyptian leadership vowed to respond to the "criminal killings".
The bombing of Libya was a unilateral Egyptian air-force strike. Relations between the el-Sissi regime and Washington are poor, and yes Washington would have watched this strike unfold in real time.
I think there is a bigger strategic point here as well. How does the West tackle these sorts of crises in North Africa and the Middle East. We have tried intervening in Libya and it has led to almost total chaos. We've tried not intervening in Syria and we are left with a humanitarian catastrophe.
So it really means that there is no template, no model for success, and we are left with what we are seeing now. A deteriorating situation right across the region.
