US President Joe Biden has offered a message of hope to the hostages Hamas kidnapped from Israel during the 7 October attacks.

Asked by journalists at an address he was giving on climate change about the hostages - now more than five weeks on from them being taken - Biden said he had been "talking to the people involved every single day".

"I believe it's going to happen but I don't want to get into detail," he said.

For the families of more than 200 hostages taken, President Biden said he had this message: "Hang in there, we're coming."
