The tension is increasing between Israel and archenemy Iran after Hamas' political leader Ismail Haniya and Hezbollah's commander Fuad Shukr were killed.
The escalation is taking place in the light of the Gaza War that began in October last year.
A source within Israel's leadership tells NBC that the country is preparing for a wave of missiles and drones, fired from Iran and its allies in the region.
They will only try to wear us out, says the source.
Drone attack on northern Israel
The Iran-backed militia group Hezbollah claims to have fired drones at northern Israel early on Monday. The attack, however, does not seem to be the more intense retaliation expected from Iran and its allies.
Two Israeli soldiers are reported to have been injured, according to Israel's military.
According to Hezbollah, they targeted a military base in response to Israeli "attacks and murders" in several villages in southern Lebanon.
Centcom in Israel
The Israeli military says on Monday that the head of the US military command for the Middle East, Centcom, has arrived in Israel to assess the security situation amidst growing fears of a regional war.
General Michael Kurilla has met with Israel's military chief Herzi Halevi and made "a joint assessment of issues related to security and strategy, as well as joint preparations in the region as part of the response to threats in the Middle East", according to a statement.
"Legal right" to respond
Iran's Foreign Ministry announced on Monday that they have a "legal right" to respond to the attack on Haniya, who was killed during a visit to Iran's capital Tehran.
No one can doubt Iran's right to punish the Zionist regime, said Nasser Kanaani, a spokesperson for Iran's Foreign Ministry, at a press conference.
At the same time, he claimed that Iran "does not seek to escalate tensions in the region".
