Israel has said it is expanding its ground operation in Lebanon with the deployment of a fourth division after another night of intense airstrikes across the south and east of the country.

The reservist 146th division was sent to southern Lebanon overnight on Tuesday, hours after Israel announced the mobilisation of a third standing division, meaning the number of troops on the ground is now likely to number 15,000.
