Four children have been killed and six injured in a suicide car bomb attack on an Afghan army convoy in eastern Afghanistan, police say.
Several soldiers and civilians were also wounded in the incident.
Meanwhile, Taleban rebels have executed three men they accused of spying for international troops and telling them the whereabouts of a Taleban commander.
The men were publicly hanged in or near Musa Qala in Helmand province, which the militants captured in February.
Suspected Taleban militants have also ambushed two government convoys in the south near the Pakistan border, killing seven Afghan police officers.
The suicide attack which killed the four children was targeting an Afghan army convoy in Mehtar Lam in Laghman province, about 100km (60 miles) east of the capital, Kabul.
Police said the children were in the vicinity when the attacker blew up his explosives-filled car near the convoy.
Reports of floods have come from four Afghan provinces
The soldiers were on their way back to base after helping flood victims in the area, a defence ministry spokesman said, according to the Associated Press news agency.
Afghan officials say floods and avalanches have killed at least 16 people in various parts of the country, as torrential rains have caused damage and driven people from their homes.
