Unidentified terrorists set a 1000-line telephone exchange on fire in Sui, disrupting telecommunications between Dera Bugti and the rest of the country. Dera Bugti District Coordination Officer Abdul Samad Lasi said that the incident occurred at midnight when unidentified terrorists broke the main gate down and set the telephone exchange ablaze. A team has been sent to restore the communications to the town, which lies 300 kilometres southwest of Quetta. Meanwhile, two homemade bombs exploded in Quetta, shattering windows but injuring no one, police said on Sunday. A bomb went off Saturday night in a field behind an empty school in Quetta. The explosion shattered windows at the school and several at nearby homes. An hour later another bomb exploded in a park in the same neighbourhood, but there was no damage, he said. No one claimed responsibility for either explosion.
