Two Kenyan police officers patrolling a city near the border with Somalia were shot dead Sunday by gunmen suspected of sympathizing with Al-Qaida linked Shebab militants, police said.

"The two officers were gunned down while on patrol," a police officer told AFP on condition of anonymity. "Their rifles have been taken away. We highly suspect these are Al-Shebab sympathizers."

The al-Qaida-linked al-Shebab, regarded by the West as a credible threat to global peace, may have pulled out of their last Somalian stronghold of Kismayo, but the new national government must move quickly to make their defeat more than a minor setback.

Analysts however warn that despite the fact that Shebab have withdrawn from the port city, peace is still elusive in the war-ravaged nation.

Al-Qaida linked Shebab rebels said on Saturday that they have abandoned the southern Somali port city of Kismayo, their last bastion in the country, a day after an assault by African Union troops.

"The military command of Shebab mujahedeen ordered a tactical retreat at midnight," Shebab spokesman Ali Mohamud Rage told Agence France Presse.

An insurgent killed a woman and wounded three people when he hurled a grenade in a busy street in Somalia's war-ravaged capital, police and witnesses said Thursday.

"The woman died as people rushed her to the hospital," said Abdi Mohammed Ahmed, a bus conductor who witnessed the attack, in Mogadishu's central K4 district.

A Kenyan soldier with the African Union force in Somalia killed six people, all thought to be civilians, when he fired on them, a spokesman for the Kenyan Defense Forces said Monday.

"Several people approached a KDF defensive position where a KDF soldier opened fire, killing six people," the army said in a statement.

Somalia's al-Qaida linked Shebab threatened Monday to kill all the country's new lawmakers, saying that an MP killed at the weekend in Mogadishu was just the first to be targeted.

"The successful elimination of Mustafa Haji Mohammed was the action of the mujahedeen who are committed to killing all MPs," a Shebab official who asked not to be named told Agence France Presse, saying the group would "kill one-by-one" all other lawmakers.

A suicide bomber killed at least eight people and severely wounded several more Thursday in a restaurant in the centre of Somalia's capital Mogadishu, witnesses said.

The attack -- the latest in the war-ravaged city where al-Qaida linked Shebab insurgents have vowed to topple the government -- was one of the first to target several new upmarket restaurants set up by the Somali diaspora.

Somalia's newly elected president Hassan Sheikh Mohamud has been moved to the secure presidential compound following an assassination bid at his hotel, officials said Thursday.

Hassan was unharmed after two blasts went off Wednesday outside the hotel where he had been meeting a visiting Kenyan delegation, but three soldiers were killed in what appeared to be an attack by multiple suicide bombers.

Somali President Hassan Sheikh Mohamud was unharmed after two blasts claimed by Shebab extremists rocked the Mogadishu hotel where he was staying Wednesday, the African Union mission to Somalia said.

"There has been a blast around the hotel where the president was. The president is safe. All the people who were inside the hotel are safe," Colonel Ali Houmed, a spokesman for the force, told AFP.

Somalia's Islamists on Tuesday dismissed as illegitimate the vote which saw outsider Hassan Sheikh Mohamoud elected president.
