Rockets have hit areas near military camps in Pakistan's south-western province of Baluchistan during a visit by President Pervez Musharraf.
Police say six rockets were fired, three of which landed near the paramilitary camp in Kohlu, a town about 220km (135 miles) east of Quetta.
A separatist group called the Balochistan Liberation Army (BLA) says it carried out the attacks.
President Pervez Musharraf is on a three-day tour of the province.
Observers say Gen Musharraf aims to win the support of local leaders for the building of a controversial dam on the Indus river in the neighbouring province of Punjab.
Separately, local residents said they heard two explosions on Tuesday night in Quetta's cantonment area where the president was staying.
A man identifying himself as Meerak Baluch called journalists and claimed responsibility for both incidents on behalf of the Balochistan Liberation Army.
Balochistan, which has rich reserves of natural gas, has been rocked by violence for much of the year.
Tribal groups in the province have been demanding more political autonomy and a greater share of the area's resources.
