Afghan authorities on Sunday alleged that hundreds of rockets had been fired into Afghanistan from Pakistan in recent days, killing a child and forcing hundreds to flee their homes.Interior ministry spokesman Siddiq Siddiqui said that more than 340 rockets had been fired into Afghanistan over the past four days, mostly landing in villages and farmland in the province of Kunar.He said,two mosques and dozens of houses had been damagedwhile about 50 families had to flee their homes.Fazilullah Wahidy, the Kunar provincial governor, separately said that at least one boy had been killed in the attacks.Cross-border shelling incidents frequently cause tension between Afghanistan and Pakistan. The border area between the two countries is seen as highly dangerous and a sanctuary for militants who launch attacks in Afghanistan. In June, Afghanistan warned that cross-border attacks could threaten improving trust and cooperation between the neighbours unless Pakistan addressed the issue. Pakistan denies any official involvement in the incidents.
