More than 200 MPs from 12 countries have committed themselves to trying to persuade their governments to impose a ban on arms sales to Israel, arguing they will not be complicit in “Israel’s grave violation of international law” in its assault on Gaza, The Guardian reported.

The letter, organized by Progressive International, a network of socialist MPs and activists focused on international justice, is seen as the best practical measure possible to bring public anger over the 30,000 deaths of Palestinians in Gaza into the heart of parliaments, where calls for an immediate unconditional ceasefire have so far fallen on deaf ears or been rejected by national governments.
