KATHMANDU: At least five persons died and thirty-two others including seven Nepalis sustained injuries in a deadly bomb attack in Kabul of Afghanistan on Wednesday.

An improvised explosive device was detonated close to the entrance of a facility run by the British security firm G4S before gunmen stormed into the compound, multiple media sources reported.

According to Bharat Kumar Regmi Deputy Chief of Mission and Acting Ambassador to India, unofficial sources confirmed that seven Nepalis were injured in the attack; they are undergoing treatment at the local hospital.

He added that the injured Nepalis were working for G4S, one of the world's largest security groups that help guard the area around the British embassy in Kabul.

UK's G4S confirmed that five of its staff including one UK national were killed in the attack. Four of those killed were Afghan nationals, as reported by the Reuters.

Talking to THT over the phone, Ministry of Foreign Affairs Joint Secretary and Spokesperson Bharat Raj Paudyal said there are reports about Nepalis being injured in the incident.

"Ministry is trying to verify the reports," Paudyal added.

Meanwhile, the Taliban has claimed responsibility for bomb and gun attack on the security firm's compound in the capital city.

Two years ago, 12 Nepalis had lost their lives in a suicide bomb attack while guarding the Canadian High Commission in Kabul.

Despite the government ban on travelling to Afghanistan for employment Nepalis have ended up there illegally in recent times.
