Israel's ambassador to the UN Gabriela Shalev lodged a complaint with UN Secretary-General Ban Ki-moon on Saturday, regarding a rise in terrorist attacks from the Gaza Strip in the last month.
She said that Palestinians had launched some 13 Kassam rockets and mortar shells into southern Israel throughout the month of September. Many attempts to plant bombs along the Gaza border were foiled by IDF troops, she added.
Shalev's complaint came after the IAF carried out two airstrikes in Gaza overnight Friday, in response to Kassam fire on the western Negev earlier in the day.
Planes attacked a northern Gaza building which the army said was being used to manufacture weapons, as well as two tunnels along the southern border with Egypt near Rafah, which were being used to smuggle weapons.
The IDF confirmed hits in both strikes.
Kassams launched from Gaza early Friday morning and late Friday night landed in the Eshkol and Sha'ar Hanegev regions, causing no casualties or damage.
Meanwhile, in related news, a Palestinian smuggler was killed in the collapse of a tunnel under the Gaza-Egypt border later Friday morning. Palestinian health official Dr. Moaiya Hassanain of the Gaza Health Ministry said the man killed was 25 years old.
Hassanain said 127 people have died in the tunnels since 2007.
