HEZBOLLAH said on the 20th, local time, that Israel bears "full responsibility" for violating a ceasefire announced the previous day after Israeli air strikes on southern and eastern Lebanon. HEZBOLLAH described the sustained strikes as "not merely a violation of the ceasefire but naked aggression and a continuation of war, therefore Israeli authorities bear full responsibility."

Iran's Revolutionary Guard said U.S. and Israeli enemies realized by the 15th day of the conflict that the situation had slipped beyond their control.

The Observer reports Prime Minister Starmer is preparing a timetable to step down and could announce his resignation as early as next Monday. The paper says the incoming MP from a Greater Manchester by-election will be sworn in next Monday and that backers claim the newcomer has secured support from more than 201 Labour MPs to trigger a leadership challenge if Starmer does not resign—exceeding half of the parliamentary Labour party and which, they argue, would leave Starmer unable to demonstrate confidence in the House of Commons. Senior Labour figures told the paper Starmer has concluded, after discussions with cabinet ministers, Downing Street advisers, union leaders and party donors, that his hold on power is no longer secure. Party insiders say he may make a clear statement on Monday; a Labour peer close to Starmer said he appears to have accepted resignation as the remaining option.
