Kenya's foreign minister has told the BBC his country has sent troops into neighbouring Somalia to target the Islamist militant group al-Shabab. Moses Masika Wetangula said Kenya was defending itself, after a spate of suspected al-Shabab kidnappings.
Witnesses described dozens of military vehicles pouring over the border, backed by planes and helicopters. Reports say al-Shabab, which denies carrying out the abductions, has begun preparing militias to fight back.
