On the day that Palestinian leaders met to seek an end to factional fighting gunmen shot dead a Muslim cleric in Gaza. He was gunned down after delivering a sermon in which he too appealed for an end to the violence involving Fatah and Hamas militants.
He was not affiliated to either group. President Mahmoud Abbas of Fatah and the Hamas Prime Minister, Ismail Haniyeh, agreed to keep rival militants off the streets after clashes in which eight people were killed.
Similar agreements have quickly broken down amid fresh bloodshed. If the latest is to last it will have to survive calls for revenge from Fatah supporters enraged by the killing of a military commander loyal to the group.
He died after Hamas guerrillas fired a barrage of rocket-propelled grenades at his house. Infighting has surged in Gaza Bank since Abbas challenged the ruling Hamas by calling for early elections after talks on forming a unity government failed.
