Mombasa, Kenya - Leaders from the across the religious divide have urged Muslims to call off planned protests Friday over the killing of a hardline Islamist preacher whose death sparked deadly riots in Kenya's second largest city.

Kenyan President Mwai Kibaki also visited Mombasa on Thursday, as an uneasy calm set in following a grenade attack that wounded four police officers the previous night.

On Monday, gunmen shot to death Sheik Aboud Rogo Mohammed, an alleged member of the al-Qaida affiliated Somali militant group, al-Shabab. Riots in the aftermath of the killing left at least four people dead, wounded several others and caused damage to some properties.
