The US Friday strongly condemned the terror attack by Pakistan-based Jaish-e-Mohammed (JeM) in Kashmir's Pulwama district and called on all countries to deny safe haven and support for terrorists. In one of the deadliest terror attacks in Jammu and Kashmir's three decades of terrorism, a Jaish suicide bomber rammed an explosives-laden vehicle into a CRPF bus in Pulwama district, killing at least 40 personnel and leaving many critically wounded.
