JERUSALEM, June 2 (Xinhua) -- Israeli military aircraft targeted sites operated by militants in the Gaza Strip early on Monday in retaliation to rockets fired into southern Israel over the past 48 hours, the army said.
Pilots confirmed direct hits on two "terror sites" in central and southern Gaza, the army said in a statement but did not elaborate.
The rocket fire and the retaliatory strike came after weeks of relative calm along the volatile border. Two rockets fired from Gaza, on Saturday and Sunday night, landed in open areas and did not cause injuries or damage.
Lt. Col. Peter Lerner, a military spokesman, said the airstrike was a response to Gaza militants' "terrorist aggression" against civilians.
"The unlawful Gaza rocket attacks, meant to terrorize, maim and kill Israelis will not be allowed to become routine. We will fulfill our obligation to defend Israel and seek out and destroy the capabilities of those who attack us," Lerner said. He noted that some 150 Gaza rockets have been launched since January.
In a separate incident early Monday, Israeli forces fired at a target in Syria after a mortar shell struck Mount Hermon, the army said.
An army spokeswoman in Tel Aviv did not confirm local media reports that artillery salvos were fired after shells fired from several locations targeted army posts on Mount Hermon, a strategic site captured by Israel in 1967, allowing only that troops fired at an undisclosed site across the border from which a single projectile was launched.
The military called the mortar attack "a blatant violation" of Israeli sovereignty, and said it had lodged a complaint with UNDOF.
Syrian mortars have struck Israeli territory along the northern border on the Golan Heights on numerous occasions in the past couple of years.
None have resulted in injuries or damage to date, and the Israeli military has attributed most incidents to errant fire from the fighting between Syrian government forces and insurgents.
