Mogadishu: Somalia`s al Qaeda-allied Shebab rebels warned today they were stepping up a bombing campaign in the war-torn capital Mogadishu; a day after a car bomb at a police station wounded two.

Shebab spokesman Sheikh Abdulaziz Abu Musab said the extremist Islamist fighters had prepared a string of suicide bombers in their battle to topple the weak Western-backed government and the African Union troops who guard it.
"The explosion which hit at the police headquarters yesterday was the beginning of a series of suicide and bombing attacks that mujahedeen fighters plan to carry out in Mogadishu in the coming days," Abu Musab told reporters.
Police said yesterday they had found another car laden with explosives close to the same station, near the busy central K4 roundabout. Two people were wounded in the heavy blast yesterday, when explosives packed into a car seized by the police were detonated, destroying part of the police compound`s perimeter wall, police said.
A man had been arrested in connection with Thursday`s blast, information ministry official Abdullahi Bile Noor said, condemning the "godless al Qaeda enemy" for the attack.
The attack was the latest in a string of blasts including roadside bombs and grenade explosions that have rocked Mogadishu in the past six months since the hardline Shebab left fixed positions and switched to guerrilla attacks. "We will continue bombing... We call on civilians to stay away from those areas where the enemy is based," Abu Musab said, adding that government officials and African Union troops were considered targets.
Police official Mohamed Abdi said security had been tightened in the anarchic city.
