Pakistani Army Chief of Staff General Qamar Javed Bajwa met with Afghan President Ashraf Ghani and other leaders in Kabul on Monday, sources told Reuters on condition of anonymity.

The media wing of Pakistan’s military did not immediately respond to a request for comment or confirm the visit.

According to Reuters, it was not immediately clear what was discussed during the meeting.

Neighbouring Pakistan is regarded as a key player in the Afghan peace process. In the past Islamabad has been accused of harbouring the Taliban but in recent years Washington and other Western powers have acknowledged its efforts to push the militant group to take part in peace talks.

Bajwa on Monday also met Britain’s Chief of Defence Staff General Nicholas Patrick Carter for talks on Afghan peacemaking, according to a statement from Pakistan’s military media wing. The venue of the meeting was not given.

In recent weeks, Taliban and diplomatic sources told Reuters, Pakistan has been negotiating with insurgents to try and get them to commit to a ceasefire, agree to an extension of the U.S.-Taliban agreement which stipulated forces should withdraw by May, and to continue to take part in peace talks at a planned conference in Turkey.

Violence has risen starkly in Afghanistan in recent weeks with the Taliban launching attacks throughout the country.

The Taliban announced on Sunday night that they would commit to a three-day ceasefire for the Islamic religious holiday of Eid later this week.
