(CNN)Rescuers are searching for two mountain climbers missing on a peak in Pakistan, including a British man whose mother died in the same region in 1995.

Mountaineers Tom Ballard and Daniele Nardi have been missing for over a week, after contact was lost with them during an ascent of Nanga Parbat, in the Himalayas.
According to a statement published on Nardi's Facebook page, "traces of (an) avalanche" were seen by rescuers near the pair's base camp during a helicopter flyover last week.
    Another post on the page, which is being updated by colleagues of Nardi's, said a team of four mountaineers landed in the area Monday, and began searching it on foot and using drones, "but no traces of Daniele and Tom were found."
    Italy's Ambassador to Pakistan, Stefano Pontecorvo, said on Twitter that efforts had resumed Tuesday. "Plan is to reach Camp 3 and search the surroundings also with the help of the drones."
