Foreign Secretary William Hague has urged both Israel and the Palestinians to make efforts to halt the violence in Gaza, but made clear that he believes Hamas bears the greatest responsibility for the current crisis, as well as the ability to bring it most swiftly to an end.
Mr Hague told BBC Radio 4's Today programme that there had been "a large increase" in rocket attacks on Israel from Gaza over recent weeks.
What Israel has done is obviously the Israeli response to that. The thing that would bring this most quickly to an end would be for Hamas to stop launching rockets at Israel.
But of course, there are also responsibilities on Israel. I spoke to the Israeli foreign minister yesterday afternoon to urge the Israelis to do their utmost to reduce tension, to take every opportunity to de-escalate the situation and observe international humanitarian law, to avoid civilian casualties.
Both sides have a responsibility to try to bring this to an end.
