A woman tells Sky News her son was killed after being shot dead near an aid centre - as the IDF says it fired "warning shots" but is not aware of any injuries.

An Israeli strike killed 15 people, including women and children, gathered outside a health center in the central Gazan city of Deir Al Balah on Thursday, according to medical staff and officials in the enclave.

With week-long truce talks looking gridlocked, another food and aid distribution point has been targeted by Israeli fire, killing 17.
