Delhi, Nov 15.—Indian troops killed 135 Pakistan soldiers in a day-long battle on Friday, a Government spokesman announced today. The fighting took place in the Shikarpur area of West Bengal, about 75 miles north of Calcutta.

The spokesman said four Pakistan battalions—about 2,800 men—crossed into India and attacked a border post.

The border security force called on regular forces for help and the Pakistanis were driven back across the border after advancing one or two miles. The Indian troops, who did not cross the border, captured large quantities of arms, the spokesman added. Indian casualties were said to have been much lighter than those of the Pakistanis.

[There has been no report of the reported battle from the Pakistan side.]

The spokesman said Pakistan artillery had been firing continuouslv along India's eastern border. He said there had been 200 violations of the Kashmir cease-fire and on the West Pakistan frontier since October 1.— Reuter.

Peter Hazelhurst writes from Delhi: Assessing her recent discussions with Mr Heath and other western leaders. Mrs Gandhi, the Indian Prime Minister, told Parliament today that India was not prepared to withdraw her troops from the Indo-Pakistan border until the crisis in East Bengal was resolved to the satisfaction of the elected representatives of the Bengalis.

In an oblique reference to suggestions that both Pakistan and India should withdraw their troops from the frontier, Mrs Gandhi said : “Obviously we cannot take risks such as the withdrawal of forces from the border unless the situation in Bangla Desh is resolved satisfactorily as if poses a serious threat to our security.”

She asked Indians to endorse her policy of restraint until the leaders of the western countries had been given a chance to persuade Pakistan to arrive at a realistic political solution with the Bengalis. She said this would create conditions in East Bengal under which the 10 million refugees now in India would return to their homes with a sense of security.

She hoped that international efforts would make President Yahya Khan realize that “no good can come of sabre-rattling or by forcing a military conflict on India”.

With a measure of reservation, Mrs Gandhi said that she had been received with sympathy and understanding during her visit to the West.

In a specific reference to Britain, Mrs Gandhi indicated that as far as the Indian Government was concerned. Indo-British relations had not been cordial since Mr Wilson supported Pakistan at the time of the 1965 Indo-Pakistan conflict.

“I think my visit also helped to restore our relations with Britain, which suffered a serious setback in 1965” she said.

Mr Jagjivan Ram. the Minister for Defence, gave a hint that the Government had already decided to recognize Bangla Desh as an independent state but added that an announcement would come at an appropriate time.

Washington, Nov 15.— Sultan Mohammad Khan, the Pakistan Foreign Secretary, said here today that his country was facing a stare of war on the Indo-Pakistan border.

Speaking to reporters after a meeting with Mr William Rogers, the United States Secretary of State, he blamed the tensions on incursions into Pakistan by guerrillas supported by Indian forces. It was only Pakistan’s restraint which has prevented the situation from getting out of hand, he added. —Reuter
