Satellite imagery has become a key tool for us to verify the impact of Israel’s military action against Iran.

The latest pictures from the specialist satellite firm Planet Labs came into us overnight which shows damage at the Tabriz North missile base in Iran following recent Israeli air strikes.

Several buildings have clearly been targeted, including at least two that have been completely flattened. There are also two large scorch marks on the ground to the east and west of the base, suggesting a fire broke out at some point.

We’ll run the images past experts to try to get a sense of what kind of facilities were targeted.

Yesterday Israel declared it had neutralised one-third of Iran’s ballistic missile launchers. Tabriz has been a regular target for Israel since hostilities escalated last week. Yesterday we reported on the effects of strikes on the city’s international airport, as well as other sites.

Welcome to Tuesday’s live page.

We’re now into the fifth day of missile and air strikes byIran and Israel as the conflict between the two sides continues.

We’re using open-source intelligence techniques to get aclearer picture of the situation on the ground in both countries – the team iscurrently looking to:

• Assess satellite imagery to get more information on which Iranian military facilities have been targeted by Israel
• Verify the impact of this morning’s Iranian missile attack on Israel – following explosions in Tel Aviv and Jerusalem

• Find evidence from social media and messaging apps to see if Iranians are heeding US President Donald Trump’s message to evacuate Tehran

We’ll also keep across the latest from Ukraine following amajor overnight drone and missile attack by Russia which is reported to havekilled at least 15 people in Kyiv.
