Islamabad: Pakistan President Pervez Musharraf today said authorities were investigating the possibility of involvement of foreign elements in the recent spate of terrorist attacks in the country.

"We are trying to find out who is behind these attacks and the causes. We are trying to find out if foreign hands are behind these attacks," he told reporters before leaving on a two-day visit to Indonesia and Malaysia.

"People involved in these attacks were misguided people who didn't understand Islam," Musharraf said adding Pakistan had to show patience in the face of terrorist attacks.

"We are trying to unearth these elements. The nation must also show patience and be united to face these attacks. The Law Enforcement Agencies are also pro-active," he said.

The Pakistan President said there was a need for the nation to face the terrorist elements with courage and if the people stayed united they could defeat them.

In the last five days, there have been at least five incidents of suicide bombings and rocket attacks on Shia Moharram processions.

Curfew has been imposed in the town of Hungu after rockets were fired at a procession and two persons were killed.

Fourteen people were killed in Peshawar on Saturday when a suicide bomber blew himself up in a congested locality of the city near a Shia mosque.
