DACCA, Pakistan, July 24— Foreigners here were warned this week to avoid Chinese restaurants, which have apparently become the latest targets for separatist guerillas.

The guerrillas' clandestine radio station, presumably broadcasting from neighboring India, was said to have reported this week that two West Pakistani officers were killed by mukti bahini, or freedom fighters, who threw a bomb into a Chinese restaraunt here.

The bombing of Chinese restaurants apparently has political or national significance except that they are popular among upper‐class Pakistanis and army officers.

During the last two weeks, bombs or grenades have exploded every night in Dacca. Thursday night three powerful blasts were heard, but their could not be determined.

Today, an army truck hit a mine in a Dacca suburb. The Pakistan army quickly imposed a curfew on the neighborhood.

Movie Houses Warned

The guerrillas have said that movie theaters in East Pakistan where the price of admission includes a government tax will be attacked. Bengali separatists sought to disrupt the Government's examination early this week for students seeking the equivalent of high‐school diplomas, throwing several grenades at examination places. Foreign sources said that only about a quarter of the registered applicants showed up to take the examination.

The most serious incident of the last week was a coordinated bombing attack Mon day night against five power transformer stations here.

According to technical observers, two of the stations were destroyed, another was moderately damaged and two were lightly damaged.

The explosions left most of the city of Dacca without electricity for nearly a day and power was restored by routing current around the damaged stations.

The clandestine transmitter, Radio Bangla Desh, reportedly announced the power station bombings in advance.

Foreigners and others have been warned to be careful when traveling in East Pakistan, especially by road. Drivers are advised to set out in the afternoon, to allow time for clearing or detonation of any mines laid during the night, and to drive in the center of the road to avoid any mines at the sides.

Attacks against bridges and other communications by the guerrillas reportedly, have in crease markedly in the last two weeks. Rail communications between the port of Chittagong and Dacca remain out.

One resident expert on the military situation suggested that Bengalis who fled to India after March 25, when West Pakistan's army moved against East Pakistan, and who enrolled in Indian guerrilla schools now had graduated and returned to Pakistan.

There are fears in some quarters that Bengali terrorism may turn against some of the 230 Americans in East Pakistan.

4th of July Blast

A grenade was thrown into the yard of the American consul's residence here after a Fourth of July party. At the time of the explosion the party was over and the residence was unoccupied.

Bengalis here frequently approach Americans to express bitterness that Washington apparently intends to continue its aid, including military supplies, to the government in West Pakistan. Local critics make sharp distinction between Americans and the British, who have adopted a hard line toward the Pakistan Government and are therefore considered the friends of Bengali separatists.

However, major British tea plantations in Sylhet district reportedly have been so badly terrorized by guerrillas that most British managers have left the plantations and tea production has plummeted.
