PESHAWAR: Assistant Political Agent Landi Kotal Khalid Mumtaz Kundi died on Tuesday from injured sustained when suicide bombers struck his office a day earlier during a meeting to discuss looming general elections, officials said.

Kundi, a deputy of Khyber Agency Political Agent Mutahir Zeb, died in a military hospital in Peshawar.

“They operated on him for several hours overnight but several pieces of shrapnel had entered his body and he died,” a security official told AFP.

Officials in the Khyber administration confirmed his death.

Six people have now died as a result of the attack, in which two suicide bombers stormed the Khyber administration's compound in Peshawar as Zeb chaired a meeting on arrangements for the elections.

There has been no claim of responsibility.

The Pakistani military has long been fighting Taliban and other insurgents in Khyber, which straddles a key Nato supply route into Afghanistan, where US-led combat troops are due to leave next year.

Violence has increased in northwest Pakistan ahead of elections, which are due by mid-May and which will mark the first time an elected civilian government completes a full term in office.
