India is seriously concerned at the escalation of hostilities between Israel and Iran that threatens the peace and security in the West Asia region, the Ministry of External Affairs said today, hours after Iran launched a drone and missile attack on Israel. "We call for immediate de-escalation, exercise of restraint, stepping back from violence and return to the path of diplomacy. We are closely monitoring the evolving situation. Our Embassies in the region are in close touch with Indian community. It is vital that security and stability are maintained in the region," the ministry has said in its statement.
