Witnesses say at least 10 people have been injured in a grenade attack on a Somali parliament member's house.

The home of Abdullahi Shaleyste in the southwestern town of Baidoa was attacked late Thursday.

The lawmaker was apparently unharmed but members of his family were injured in the blast. At least four of the wounded are said to be in serious condition.

No one has claimed responsibility for the attack.

Islamist insurgents have waged a bloody 17-month battle against Somalia's Ethiopian-backed interim government.

The government and exiled opposition leaders who back the insurgents are set to resume reconcilation talks in Djibouti on Saturday.

However, leaders of the Eritrean-based Alliance for the Re-Liberation of Somalia appear split on whether the group should be holding the talks.

Hard-liners in the group say no talks should take place until Ethiopia withdraws its troops from Somalia.
