NAIROBI, Jan. 16 (Xinhua) -- Kenyan Prime Minister Raila Odinga on Saturday ordered investigations into Friday's demonstrations called by Kenyan Muslims to protest the arrest of controversial Jamaican Muslim cleric Sheikh Abdullah al-Faisal.

Odinga instructed Internal Security Minister to carry out comprehensive and urgent investigations into the riots that left at least five people dead and the fatal shooting of protesters.

"The PM also appealed to the Muslim community to remain calm and give the government time on their grievances," a statement said.

The peaceful protest turned violent as the marchers pelted police officers with stones who in turn fired in the air and lobbed tear gas canisters.

Several people including police officers were among those who were seriously injured in the protest while some of them were stabbed by the demonstrators.

Shops adjacent to the mosque were looted and vehicles that were parked on the streets had their windscreens smashed by stone-throwing youths.

Angry members of the public joined in the melee and helped police confront the advancing Muslim youths.

Odinga said in the statement that the confinement of the clerics a sensitive security matter that the government is handling delicately and it should be given time.

The PM also said the police must desist from using live ammunition to quell riots.

"Use of live bullets has led to loss of lives before and it is something police must do everything possible to avoid," the PM said.

The Jamaican preacher was deported from Nairobi last week following orders by Immigration Minister. Al-Faisal, born Trevor William Forrest, was convicted in Britain on terrorism-related charges in 2003 and was deported from Britain in 2007.

On arrival in Jamaica, the Islamic Council of Jamaica banned him from preaching in its mosques. The Kenyan authorities held Al-Faisal at the country's main airport last week as they plotted his next destination.

Kenya had flown him to Lagos, Nigeria. From there, he was scheduled to fly to Gambia and then to Jamaica. But airlines in Nigeria refused to fly him to Gambia.

Kenyan authorities reportedly drove him to the border of Tanzania last Tuesday because he had entered Kenya from there, but Tanzania refused his entry.
