Kathmandu/Islamabad: A Pakistani embassy official was shot by unidentified motorcycle-borne gunmen outside the mission building in the capital city of Nepal. Islamabad has voiced concern over the attack.

Mehboob Asif, a visa section officer, was shot as he stepped out of the embassy building at Basundhara in the outskirt of the capital.

He was shot three times, police said adding that his assailants, who were riding on a motorcycle, managed to escape. Asif was rushed to the Tribhuvan University Teaching Hospital (TUTH) in Maharajgunj with bullet wounds in his stomach, police said, but described his condition as stable.

In Islamabad, a Foreign Office spokeswoman Tehmina Janjua said the official was an assistant counsellor in the embassy. "We have taken up the matter with the Nepalese government," she said.

The Kathmandu police launched a massive manhunt for the killers and rounded up over 100 suspects for questioning.

The shooting of the Pakistani visa officer comes after a recent gesture of gun attacks in the capital by unidentified gunmen, fuelling concern over public security.
