Tehran reserves the right to react Israeli airstrikes last month on Iran but also bears in mind other developments in the region, Iranian Foreign Minister Abbas Araghchi said on Wednesday. Araghchi told reporters during a trip to Lisbon that Iran welcomed Tuesday's ceasefire agreement in Lebanon and hoped it could lead to a permanent ceasefire.

A ceasefire deal that went into effect on Wednesday could end more than a year of cross-border fighting between Israel and Lebanon’s Hezbollah militant group, raising hopes and renewing difficult questions in a region gripped by conflict.

Israel said it had targeted militants headed to a rocket facility, but neither Israel nor Hezbollah seemed keen to immediately return to full-scale fighting.
