Hello I'm Lees Dusset, the BBC's chief international correspondent. I'm in Jerusalem, and it's

one year since the horrific events of October the 7th, the deadliest day in Israeli history. The day Hamas fighters went on a murderous rampage

and towns and kibbutz's across southern Israel. It triggered a devastating war in Gaza, an unprecedented hostage crisis, and sparked what is now the darkest, most dangerous moment in this region.

One year on it's a moment to look back at how this war began, how it intensified in Gaza, and

how month after month tensions and violence have escalated across the region, drawing in armed groups linked to Iran, what it calls its

axis of resistance, militias it's armed in Iraq, Syria, Yemen, and most of all Lebanon, where Iran's closest ally Hezbollah is in Israel's

sites more than ever before, and arch-enemies Iran Israel, in direct confrontation. One year on this is a war ringing alarm bells

in capitals across the region and around the world and causing unprecedented pain for people in the region, taking this age-old

conflict into perilous, unpredictable terrain. Thank you for joining us as we take a look back at the

dramatic events which have unfolded in southern Israel, in Gaza and across the

region over the past year. We want to reflect on all that's happened

and look to where this war unprecedented in so many ways may now be heading.

This is the conflict one year on. On October 7th, 2003, Hamas fighters broke through Israel's much-vaunted security barrier and stormed through towns and kibbutz's across southern Israel. By the end of the day, 1,200

people were killed and 251 Israelis and foreigners were taken hostage, and was an

unprecedented day, seared in Israeli memory.

One year on, around 100 hostages, are still being held in Gaza. Many fear dead. And Gaza

now lies in ruin. The UN says more than 41,000 Palestinians have been killed, most of them women and

children. The violence and suffering has spread to the occupied West Bank and across the region,

escalating in recent weeks to an Israeli ground invasion of Lebanon and growing tension between two arch enemies, Israel and Iran.

And we're joined now by three colleagues, first of all to Jeremy Bowen, our international

editor. Hello Jeremy. Hello our international editor.

Hello, Jeremy.
