Pakistan's Interior Ministry said on Tuesday that authorities arrested dozens of suspects, including the brother of the leader of the outlawed Jaish-e-Mohammad group that India blamed for the February 14 suicide bombing in Indian Kashmir that killed 40 troops.
The bombing triggered a dangerous escalation that pushed Pakistan and India close to an all-out war over Kashmir.
In Tuesday's statement, the ministry said 44 suspects were arrested, including prominent members of the outlawed militant group. Among those arrested was Mufti Abdul Rauf, the brother of the group's leader, Masood Azhar.
The ministry says the brother was among suspects listed in a file on the February bombing that India gave to Pakistan over the weekend. Kashmir is split between Pakistan and India and is claimed by both in its entirety.
